Along with radar's equipment, the modern fighter aircraft already might penetrate the dark night and the fog, has the beyond line of sight detectability. Adapts with it, the people hoped naturally can have with it necessary attack ability, thus may attack a farther place the goal, the simple the method is also provides the radar for the missile, its may survey a farther goal.
Those who possibly stem from many people to anticipate is the active radar guidance radar guiding air-to-air missile's appearance must be earlier than the semi-active radar guidance air-to-air missile. As early as in the 1950s, the US started to attempt the development to use the active radar to guide the house sparrow the air-to-air missile (serial number is AAM-N-3). But the matter has not imagined that simply, we knew that parameters and so on radar range and radar antenna area, transmitter power, receiver sensitivity assume the proportional relationship. Because missile's diameter is small, the inner space is limited, therefore in the microwave device technology limited situation, very difficult to do installs the missile internal radar, therefore presented the simplified radar control way - - semi-active radar guidance, is also AIM-7 which is familiar with by everybody the house sparrow the series air-to-air missile.
The semi-active radar guidance in fact is the volume and the difficulty big antenna, above the launch turning point migration fighter aircraft, but the missile only leaves behind the receiver and the control mechanism, also let the air fight henceforth enter the beyond line of sight time. However this kind of guidance mode's limit is also obvious: In the guided flight process, the fighter aircraft needs to shine the goal throughout, therefore has limited the carrier vehicle and missile's mobility, easily by opposite party disturbance and attack, moreover is unable to attack many goals, when copes with under the low altitude and the serious noise jamming goal ability is more limited.
Along with the modern battle airplane's development, its performance was specially the speed and the maneuvering performance had the big enhancement, this means that the air fight battle the time was getting more and more short, the fighter aircraft needed attack more goals as far as possible in an attack. And has the low altitude high speed defense penetration ability aerial warfare weapon's appearance like fighter bomber, the cruise missile also to need the battle airplane to have the better downward looking undershoot ability. In this case, each major country starts to develop the active radar guidance air-to-air missile. Only the radar echo receiver is different with the semi-active radar detection unit, the active radar detection unit has simultaneously installed the missile-borne radar transmitter and the receiver. Was equal has had the independent search and lock onto target ability in missile. Certainly, the missile-borne radar the transmitter volume and the power, limits and so on radar antenna size is impossible to achieve the aircraft-borne fire control radar's searching range, is impossible to discover the goal independently, and flies completely independently.
What but is different with the semi-active radar guided missile, the active radar guided missile does not need carrier vehicle's airborne radar approach to carry on the long-enduring illumination guidance, but needs carrier vehicle's airborne radar approach merely once in a while on refurbishing one time with the goal connection predetermined fiducial mark data. This data message may give the missile through the airborne radar approach side lobe direct cochain also to be possible through carrier vehicle's data chain transmission to missile's missile-mounted unidirectional data chain. After the missile accepts the predetermined convergence point coordinate, its correspondence to inertial instrument system's coordinate system, the missile defers to the inertial guidance system's guidance to face independently this coordinated flight. This greatly reduced the target machine mobile to the missile energy response influence.
in 1976 the United States Air Force basis to 2000 around the air fight environment's analysis, proposed that develops beyond line of sight, the active radar guidance air-to-air missile, this is advanced medium range air-to-air missile plan - AMRAAM, is also the present famous AIM-120 active radar guidance air-to-air missile.
in 1981 AIM-120 carried on for the first time the test fire, in 1984 completed the production configuration AIM-120 winding, in 1988 the design finalization of the design, the delivery small batch production, in 1991 served, and attended same year's Persian Gulf War, as a result of the Iraqi Air force already operational capacity, therefore has not attended the actual combat, in 1992 AIM-120 obtained the first victory, a F-16 fighter aircraft the airspace reservation used AIM-120 south Iraq to shoot down Iraqi Air force's Mig - 25 fighter aircrafts for the first time, hereafter AIM-120 took American and the NATO allied country main force aerial warfare weapon, since attended the 90s's all previous war, shot down about each kind of battle airplane 10, including 6 third generation Mig - 29 fighter aircrafts, appearanceThis missile good technique and tactics performance. Besides the US, former Soviet Union/Russia and France have also developed the own active radar guidance air-to-air missile, and was operational one after another in the 1990s.
However in the AIM-120 victory including 2 American MH-60 the black hawk the helicopter, the reason was at that time these two airplanes had not opened the friend-or-foe identification, caused the F-15 fighter aircraft to take for is opposite party goal, this matter in fact showed the active radar guidance air-to-air missile, although the performance was fine, but its performance's display still depended on the entire air fight system's coordination, including the aircraft-borne fire control radar, the data chain, outside the foe identification, a early warning and the direction guidance was systematic forming a complete set.
Also some classical model, in the past Luftwaffe's F-4ICE, although has equipped AIM-120, but still relied on the voice to carry on the air fight to direct, but Britain's strong winds F3 airplane, although equips is the sky flash semi-active radar guidance air-to-air missile, but has provided the advanced LINK-16 data chain, relied on the LINK-16 composition the union network air fight system, strong winds F3 defeats F-4ICE, the appearance active radar guidance air-to-air missile's might display even more could not leave the complete air fight to direct the guidance system's support, the former let the latter's attack ability forward long cross one step, then the latter enhanced the more comprehensive target information, let the missile be able to hit farther and.
Front had said AIM-120 founded the active radar guidance air-to-air missile time, is also is most advanced at present, has obtained the victory this type missile only, at present AIM-120 had already developed the nearly ten models, provides above the Western country nearly all battle airplane, the equipment country surpasses 20, the output surpasses 10,000, and had already developed the surface-to-air missile, further expanded its use scope.
The AIM-120 missile's main model including AIM-120A, AIM-120B, AIM-120C, AIM-120C-5, AIM-120C-7, AIM-120D, AIM-120A is the ground form, the bullet weight 157 kilograms, the length of projectile 3.65 meters, the diameter 0.18 meter, the wingspan 0.52 meter, the rudder unfolds 0.62 meter, greatest speed M4, the maximum range 80 kilometers, production quantity surpasses 5000; AIM-120B, AIM-120C, AIM-120C-5, AIM-120C-7, AIM-120D are the promotion improvement models. In the promotion improvement process, the AIM-120 unceasingly undersize and the volume, the replacement thrust force bigger solid propellant engine increases the missile range, simultaneously enhances missile homing head's data processing and anti-electronic countermeasure ability, when to newest advanced version AIM-120D, the performance has been able to enhance largely.
AIM-120D used a thrust force bigger engine, the maximum range enhanced to 140 kilometers, to avoid the guidance accuracy which the firing distance increased brings dropping, it used the compact GPS/inertial measurement unit to reduce missile's alignment error. After it also used the bidirectional data chain caused the missile launching, has been possible to the carrier vehicle sending back goal related information, enhanced the long-range combat effect. AIM-120D strengthened the missile big off-boresight angle battle ability, this caused it to have the bigger attack scope, even might attack after death goal. In addition, because uses the bidirectional data chain technology, can allow another fighter plane to control the guided flight, but after letting the carrier vehicle launches missiles, leave immediately, thus enhanced carrier vehicle's attack element of surprise and carrier vehicle's survivability.
The tendency which develops according to the world air fight, started the China Air Force to the last century the 60s to begin to develop the new generation operational capacity, had including the equipment 206 intercepts the radar and the thunderclap - 4 medium-range air-to-air missiles annihilates the - 9 fighter aircrafts, to have the airborne early warning subsystem's automation air defense control homing system, these will constitute the China Air Force new generation aerial defense system, but because economical technology base weak and other reasons, many key equipments have not been able to make the breakthrough slowly.
Since the 80s, China uses the advantageous international environment, uses independently develops the means which and the introduction technology unifies, develops the Chinese first kind to have the beyond line of sight operational capacity F-8 II fighter aircraft successfully, this machine has composed the Chinese first kind of semiautomation air defense control homing system through 483 data chains with 1125 ground control homing system. Symbolizes that China Air Force operational capacity and the aerial warfare weapon development has achieved a new level.
However at that time the F-8 II fighter aircraft used was mainly the thunderclap 8 semi-active radar guidance air-to-air missile which comes by the Italian Ards Parke Davis Co semiactive guidance radar air-to-air missile imitation. Although the thunderclap 11 has achieved the imitation prototype Ards Parke Davis Co performance parameter (Ards Parke Davis Co semiactive guidance radar air-to-air missile's predecessor is basically US's house sparrow air-to-air missile), but the semi-active radar guides the inherent flaw lets its and is insufficient to take on the China Air Force main force armament system's role.
SD-10 (Chinese official serial number: The thunderclap 12) the medium range air-to-air missile already was the China Air Force active duty three generation of machine main action equipment. Small chart for development when introduces Russian 9B-1103M active radar detection unit.
Since the 90s, along with the developed country active radar guidance air-to-air missile's service, China also starts to begin to develop the new generation active radar guidance air-to-air missile, in 1997 the China Air-to-Air Missile Research Institute started to develop new missile SD-10. Considered at that time the domestic technology base was still weak, the new missile introduces Russian 9B-1103M active radar detection unit. 9B-1103M is the Russian AGAT Research institute to substitute R-77 the first generation of 9B-1348 detection unit development the new active radar detection unit, it sharpened the signal processing ability, the computer operating speed has provided to 50,000,000/seconds, the memory enhances 64K, the probing range enhances from 16 kilometers to 25 kilometers about, has substituted the latter's mechanical top with the optical fiber top, might fast preheating, let the missile complete rapidly from the ready condition to the state of action transformation.
SD-10 has attacked and captured questions one after another and so on shell body intensity, bomb rack interference in the development, completed the test fire in 1998, in 2005 the design finalization of the design, and completed the Chinese double goal attack experiment for the first time in the same year, symbolizes that the domestically produced air-to-air missile entered the multi-objective attack time. According to the overseas material SD-10 missile size for the length is 3.51 meters, the diameter 0.21 meter, the wingspan 0.67 meter, the launching weight 180 kilograms, uses the dual thrust solid propellant engine, the maximum rate of fire is 4M, the maximum range above 70 kilometers. Performance and AIM-120A missile quite. After SD-10 develops successfully, China continues to make the improvement, developed the SD-10A air-to-air missile, SD-10A sharpened missile's maneuver capability successfully, simultaneously strengthened the shell body intensity, the weight also increased to the nearly 200 kilograms.
The SD-10 active radar guidance air-to-air missile is the China Air Force new generation air fight system's important component, the new century China Air Force battle airplane aircraft-borne fire control radar performance had enhanced greatly, has provided the union-like navigation electricity system and the vitrification cabin, at the same time, the early warning aircraft - 2000 large-scale early-warning aircrafts, the automated direction homing system, the data chain developed one after another successfully, already initially formed the union network combat system, China Air Force's air fight ability enhanced to a new level, and has built the solid foundation for the later establishment complete network combat system.
Although SD-10The performance is fine, but this missile also has certain shortcoming, (AIM-120A only weight 157 kilograms) compares with US's AIM-120 medium range air-to-air missile, its volume and the weight are obviously big, therefore is big in the equipment in the small battle airplane to its performance influence. If provides when the JF-17 wing approaches the flank the gallows, before needing the gallows, to extend adjusts the center of gravity. What some point is also not allow to neglect is China is developing the fourth generation of fighter aircraft, at the appointed time will use buries the missile bay to sharpen airplane's stealth ability. If the volume is big, immediate influence China fourth generation of fighter aircraft's bomb-carrying capacity, therefore SD-10B will take one section to provide the domestically produced four generation of machine air-to-air missiles besides to in the future carry on the performance the essential promotion, but must be the same with the AIM-120C series, has carried on certain deflation to missile's volume and the weight, will enhance the missile to carry the scope suitably and to hang carries ability.
What SD-10B is most noticeable was it has it is said used main/passive the compound terminal guidance system, what needed to point out was the medium range air-to-air missile already has the passive guidance ability, this was the noise source guidance mode, was the missile in the attack process, if goal distort, missile guidance antenna on transformation radio noise signal, attack noise source. However from the report analysis, SD-10B should not use the noise source to guide this way, but has used the main/passive combined guidance detection unit, in fact SD-10B was not the first plan uses this kind of detection unit's air-to-air missile, AIM-120 once planned the addition passive radar detection unit, but Russia also once developed develops the 9B-1032 passive radar detection unit successfully, provided above the R-27 missile, but after improving R-27 was only the pure passive guidance way.
AIM-120A missile's detection unit. Now the medium-range ball has the noise source guidance mode this kind of passive guidance ability generally, but the author analyzed SD-10B possibly to use the main/passive combined guidance detection unit.
Is different with the noise source guidance, the main/passive combined guidance detection unit increases the passive guidance way receives opposite party airborne radar approach electric wave, needs the passive receive is the unidirectional received signal, therefore the signal strength two-way transmission radar electric wave signal is high, this was equal in increasing radar's power, was away from the formula according to the radar, the radar range and the emissive power presents the direct proportion, but regarding the inner space limited air-to-air missile, raises the emissive power to be quite difficult, therefore increased the passive radar guidance system to be possible to enhance the terminal guidance radar's probing range from the certain extent.
But it also has in big technical the difficulty, the first passive guidance system frequency is wide, the precision is bad, specially the airborne radar approach was the high speed movement goal, the new generation active phased-array radar has used the twinkle and the burst and so on low probability of interception working pattern, therefore the air-to-air missile new host/passive guidance system request could both be able also to work, enhanced to the goal pointing accuracy.
Also has is the cloth buyer/passive guidance system is quite simultaneously difficult in the limited shell body space, at present solves the means are the main/passive guidance system use in common an antenna, forms the broadband combined antenna, meanwhile must solve technical difficulties and so on wide band antenna cap, high sensitivity wide-band receiver, specially two guidance system also works, needs to solve two kind of guidance intelligence information fusion problem. Therefore did not have the system-related investment practical report at present. If the SD-10B equipment is this kind of detection unit really, that indeed is a Chinese missile technical level significant breakthrough.
The Pakistani Air force uses the SD-10B medium range air-to-air missile to mean that the Fierce Dragon fighter plane will continue to use China's navigation electricity system, the Fierce Dragon fighter plane also will provide in the future the active phased-array radar, coordinates China the ZDK-03 early-warning aircraft which is providing to Pakistan, will enhance this machine air fight performance largely inevitably, and will form new generation's air fight system. The Fierce Dragon fighter plane also definitely might at the appointed time resist the equipment to have the BARS passive phased-array radar and R-77E medium range air-to-air missile's Indian Air force Soviet - 30MKI fighter aircraft, thus improves the present Pakistan's in Indian-Pakistani Air force contrast inferiority situation greatly.
Those who possibly stem from many people to anticipate is the active radar guidance radar guiding air-to-air missile's appearance must be earlier than the semi-active radar guidance air-to-air missile.
