SD-10B will have a reduced volume weight
Although the excellent performance of SD-10A, but there are some of the shortcomings of the missile, and the United States in the distance AIM-120 Missile (AIM-120A weighs only 157 kg) than its larger size and weight obviously, so with smaller aircraft in combat a greater impact on its performance. 如配备在JF-17机翼靠近外侧的挂架时，需要挂架前伸以调节重心。 If equipped with the JF-17 near the outer wing pylons, the pylons need to reach to adjust focus. 还有一点不容忽视的是中国正在研制第四代战斗机，届时将采用内埋弹舱以提高飞机的隐身能力。 Another point should not be overlooked is the fourth-generation fighter aircraft being developed, will be buried inside the bomb bay used to enhance the aircraft's stealth capabilities. 如果体积较大，将直接影响中国第四代战斗机的载弹量，所以SD-10B作为一款未来将配备国产四代机的空空导弹除了要进行性能上的必要提升外，还要和AIM-120C系列一样，对导弹的体积和重量进行了一定的缩减，以提高导弹的适载范围和挂载能力。 If larger, it will directly affect China's fourth-generation fighter load of bombs, so the SD-10B made as a four generations of the future will be equipped with machine-air missiles in addition to the need to improve on the performance, but also, and AIM- 120C series, as the size and weight of the missile, which must be reduced to improve the relevance of the missile range and mount capability set
SD-10B may be equipped with the Active / Passive Composite Seeker
SD-10B is said the most striking is its use of the "active / passive" composite terminal guidance system, be pointed out that in the long range air to air missile with passive guidance capability, which is the source of interference guidance system, that is, the process of missile attack interference in the cast if the target, the missile guidance antenna conversion receiver interference signal to attack the source of interference. 不过从报道分析，SD-10B应该没有采用干扰源制导这种方式，而是使用了主/被动复合制导导引头，实际上SD-10B并不是第一个计划采用这种导引头的空空导弹，AIM-120就曾经计划加装被动雷达导引头，而俄罗斯也曾经研制成功研制出9B-1032被动雷达导引头，配备在R-27导弹上面，不过改进后的R-27只是单纯被动制导方式。 But from the reports and analysis, SD-10B should not be guided by the source of interference in this way, but the use of the Active / Passive Composite Seeker, in fact, is not the first SD-10B plan to use this air to air missile seeker , AIM-120 was planned to install a passive radar seeker, and Russia has also been developed successfully developed 9B-1032 passive radar seeker, is equipped with top of the R-27 missiles, but improved simply a passive R-27 guidance system
Source of guidance and interference is different from Active / Passive Composite Seeker add passive guidance system is to receive each other's airborne radar waves, requires a one-way passive receiver to receive signals, so the signal strength of radio signals over high bidirectional transmission of radar, this very on increasing the radar's power, under the radar range equation, radar detection range and the present transmission power is proportional to, and limited internal space for air to air missile, it is difficult to improve transmission power, so adding a passive radar guidance system can be improved to some extent terminal guidance radar detection range.
But its also great technical difficulties, the first frequency of the passive guidance system wide, less accuracy, especially in airborne radar target is a high speed, next-generation active phased array radar and uses flash and burst, etc. low probability of intercept mode, so the new primary air to air missile / passive guidance system requires the ability both to work simultaneously in order to improve target location accuracy.
There is limited space within the same missile body furnished master / passive guidance system is difficult, the current solution is the Active / Passive guidance systems share a common antenna to form a composite broadband antenna, and also solve the broadband antenna cover, high sensitivity Broadband receivers and other technical difficulties, in particular, there are two guidance systems work simultaneously to solve two kinds of guidance information, information fusion problem. 所以目前还没有相关系统投入实用的报道。 So there is no related systems into useful reports. 如果SD-10B真的配备是这种导引头，那的确是中国导弹技术水平一个重大的突破。 If the SD-10B is equipped with this is the true seeker, it is indeed a significant level of Chinese missile technology breakthrough.
Pakistan Air Force in the use of SD-10B from the air to air missiles means Xiaolong fighter will continue to use China's avionics system, the future Xiaolong fighter will be equipped with active phased array radar, in line with China forward in the ZDK-03 Pakistan-based early warning aircraft bound to a substantial increase in air combat aircraft performance, and the formation of a new generation of air combat system. 届时枭龙战机也将完全可以对抗装备有BARS无源相控阵雷达和R-77E中距空空导弹的印度空军苏-30MKI战斗机，从而大大改善目前巴基斯坦在印巴空军对比中的劣势处境。 Xiaolong fighters will also be fully equipped with BARS against the passive phased array radar and the R-77E air to air missiles in the Indian Air Force from the Su-30MKI fighters, which greatly improve the contrast of Pakistan Air Force in the India-Pakistan situation of disadvantage.
而单从性能上来看，SD-10B重量在180公斤左右，最大动力射程约100公里，作战性能应该与美军现役AIM-120C5相当，与美国最新型的AIM-120C7和在研的AIM-120D仍有较大差距。 And just from the performance point of view, SD-10B weight of 180 kg, the maximum dynamic range of about 100 kilometers, the U.S. military operational performance should be quite active AIM-120C5, and the United States, the latest model of AIM-120C7 and AIM-120D in the study of there is still a wide gap.
