Zhuk-ME vs AN/APG-68(V9) vs N-011M BARS vs KLJ-7
posting an article i've found , however klj7 specs might be wrong-- open for disscussions..

Official Specs Zhuk-ME says on board Mig-29K Mig-29SMT & upgrade has a detection range of 120km for a 5m2 target. Hence: Henco:
For 20m2, Zhuk-ME detection range is 170km For 20m2, Zhuk-ME is 170km detection range
For 15m2, Zhuk-ME detection range is 158km For 15m2, Zhuk-ME is 158km detection range
For 12.5m2, Zhuk-ME detection range is 151km For 12.5m2, Zhuk-ME is 151km detection range
For 10m2, Zhuk-ME detection range is 143km For 10m2, Zhuk-ME is 143km detection range
For 8.5m2, Zhuk-ME detection range is 137km For 8.5m2, Zhuk-ME is 137km detection range
For 3m2, Zhuk-ME detection range is 106km For 3m2, Zhuk-ME is 106km detection range
For 1m2, Zhuk-ME detection range is 80km For 1m2, Zhuk-ME detection range is 80km

Official Specs says N-011M BARS onboard Su-30MKI has a detection range of 140km for a standard Russian RCS, in this case 5m2. Specs official says N-011M BARS onboard Su-30MKI has a detection range of 140km for a Russian RCS standard, in this case 5m2. Indian fan boys claim that some N-011m BARS radars variants have a high power output of 7kw(the original one has only 4-5kw), and hence a higher range than the 140km given above. Indian fan boys Claim That Some N-011m BARS radars variants Have A high power output of 7kw (the original one has only 4-5kw), and Henco A Higher Than the 140km range Given Above. The precise range for this version is not known. The required range for this version is Not known. Whether this radar is inservice with the Indian Air force is also not known. Whether this is inservice radar with the Indian Air Force también Not known. And even if it is with the IAF, how many 7kw N-011M BARS radar equipped Su-30MKI there are is impossible to determine. And Even if it is with the IAF, How Many 7kw N-011M BARS radar Equipped There Are Su-30MKI is impossible to determine. Hence under these circumstances, only an official brochure can be taken into account. Henco Under These Circumstances, only an official brochure Can Be taken Into account. Official brochure, says ZHUK-MSFE with a 8kw power output, has a range of 180km for a 5m2 target. Official brochure, Zhuk-MSFE says 8kw with a power output, has a range of 180km for a 5m2 target. ZHUK-MSFE is the latest Russian radar, while BARS is several years older. Zhuk-MSFE is the latest Russian radar, while BARS Is Several Years Older. Also BARS output is lesser than Zhuk-MSFE. Also output is lesser Than BARS Zhuk-MSFE. Hence it's safe to assume 4-5kw BARS variant's(or even the 7kw range) range isn't going to be higher than ZHUK-MSFE. Henco it's safe to assume 4-5kw BARS variant's (or events the 7kw range) range isn't going to Be Higher Than Zhuk-MSFE.

140km detection range for 5m2 target. 140km detection range for 5m2 target. Hence: Henco:
For 8.5m2, BARS detection range is 160km For 8.5m2, detection range is 160km BARS
For 3m2, BARS detection range is 123km For 3m2, detection range is 123km BARS
For 1.5m2, BARS detection range is 104km For 1.5m2, detection range is 104km BARS
For 1m2, BARS detection range is 94km For 1m2, detection range is 94km BARS

Official Specs says KLJ-7 onboard JF-17 has a detection range of 105km for a 5m2 target. Specs Official says onboard KLJ-7 JF-17 has a detection range of 105km for a 5m2 target. However, PAF isn't too fond of his radar eventhough it has the same range as a APG-68(V)9 on F-16block52 & RDY-2 on Mirage-2000-5/-9(both radars according to official specs), & less range than RC-400 radar. However, PAF isn't too fond of historical radar eventhough it has the Same range as the APG-68 (V) 9 on F-16block52 & RDY-2 on Mirage-2000-5/-9 (According To Both radars official specs ), & less Than range RC-400 radar. Even in its most powerful form(meaning the version with the largest antennae, which the JF-17 cannot house due to its relatively small nose), the RC400 has 20% less range than the RDY radar. Even in ITS MOST Powerful form (meaning the version with the largest antennae, the JF-17 Which Can not house due to STI Relatively small nose), the RC400 has 20% less Than the RDY radar range. RC-400 is the radar which the PAF are planning to equip their second block of JF-17. RC-400 is the radar Which Are the PAF planning to equip Their second block of JF-17. Why they are dumping a better radar(according to official specs) and going for a lesser ranged one is fueling speculation that KLJ-7's true specs is lower than publicized. Why They Are Better radar dumping (According to official specs) and going for a lesser one is Fueling speculation ranged That's true KLJ-7 is Lower Than publicized specs. In any case, lets see what its ranges are: In Any case, lets see What STI ranges are:

105km detection range for 5m2 Target. 5m2 105km detection range for Target. Hence: Henco:
For 20m2, KLJ-7 & APG-68(V)9 detection range is 149km For 20m2, KLJ-7 & APG-68 (V) 9 is 149km detection range
For 15m2, KLJ-7 & APG-68(V)9 detection range is 138km For 15m2, KLJ-7 & APG-68 (V) 9 is 138km detection range

RCS figures are confidential. Are RCS figures confidential. However unofficially there are some figures available on the internet. However unofficially There Are Some figures available on the internet. They are: They are:

Clean(meaning payload/ammunition not loaded) F-16 after Block 30, which includes block 52 - 1.2m2 Clean (meaning payload / not loaded ammunition) F-16 Block after 30 s, which includes block 52 - 1.2m2
Clean Mig-29B & Mig-29SMT - 5m2 Clean Mig-29B & Mig-29SMT - 5m2
Clean Su-30MKI - 10m2 to 15m2 Clean Su-30MKI - 10m2 to 15m2

JF-17 without RAM, its RCS would be more than a Clean F-16 block 52 which has RAM & is planform. JF-17 Without RAM, ITS RCS Would Be More Than a Clean F-16 block 52 Which is you RAM & planform. F-16 block25 & the previous variants, which are planform in construction but without RAM, were said to have an RCS of 3m2-5m2, when clean. F-16 block25 & the previous variants, Which Are in construction planform But Without RAM, Were Said to Have an RCS of 3m2-5m2, when to clean. JF-17's TWR isn't very high, and adding RAM would mean increasing the weight. JF-17's TWR isn't very high, and Adding RAM Would Increasing the mean weight. So we can expect little or no RAM on JF-17. So we CAN expect little or no RAM on JF-17. Also, JF-17 isn't very planform in construction but has DSI and is a smaller aircraft. Also, JF-17 isn't very planform But you DSI in construction and is a Small Aircraft. So lets consider a favorable assumption that the RCS of a clean JF-17 is as low as 2.5m2. So lets Consider a favorable Assumption That the RCS of a clean JF-17 is as low as 2.5m2.

Su-30MKI's RCS when carrying full 8000kgs AG load is said to be 20m2. Su-30MKI's RCS When Carrying full load 8000kgs AG Is Said to Be 20m2.

Lets take Su-30MKI's clean RCS as 11.5m2, higher Than a standard Su-27, due to canards & the extra seat.

Mig-29K's RCS is officially confirmed to be 4-5 times less than a old Mig-29, due to composites & RAM. Mig-29K's RCS is Officially Confirmed To Be 4-5 Times Less Than the old Mig-29, due to composites & RAM. So taking an average value between 4 & 5 = 4.5. Taking an average value So entre 4 & 5 = 4.5. When the unofficial RCS of 5 is divided by 4.5 we get an RCS of 1.11. When the unofficial RCS of 5 is Divided by 4.5 we get an RCS of 1.11.
"Considerable increase of flight range is also gained due to increased capacity of drop fuel tanks and in-flight refueling capability (with the possibility to refuel from the aircraft of the same type). Due to special coatings Mig-29K radar reflecting surface is 4-5 times smaller than of basic MiG-29." "Substantial Increase of flight range también INCREASED Capacity Gained due to drop of fuel tanks and in-flight refueling capability (with the Possibility to refuel from the aircraft of the Same type). Due to special coatings MiG-29K is 4 radar Reflecting surface Smaller Than -5 times of basic MiG-29. "


JF-17 Can not carry larger payloads. Its load carrying capacity is only 7900lbs or less than 3600kgs. Its load carrying capacity is only 7900lbs 3600kgs or Less Than. This compared to Su-30MKIs 8000kgs, Mig-29k's 5500kgs, & F-16's 7500kgs. This Compared to Su-30MKIs 8000kgs, 5500kgs Mig-29K's, & F-16's 7500kgs.
Empty weight of the aircraft is 14520lbs for JF-17, 19700lbs for F-16 Block 52, 25573 for Mig-29SMT, 28550lbs for Mig-29K & 40565lbs for Su-30MKI. Empty weight of the aircraft is for JF-17 14520lbs, 19700lbs for F-16 Block 52, 25573 for Mig-29SMT, 28550lbs for Mig-29K & 40565lbs for Su-30MKI.

Both 14th insistute and the National Radar/Electrionics Insititue (NREI) have produced prototype AESA radars for J-20, both prototype radars are X-band AESA radar and contain 2000+ T/R modules, there is a open competition there and 14th insitute won the competition easily (14th insistute is considerably larger and finanically stronger than NREI), thus their AESA has been selected as the radar for this fighter roughly 2 years ago.

some guys ( very reliable guys in cdf)disclosed.

j10b AESA will have 1200 T/R modules。J20 AESA will have 2200+ T/R modules.

some new info , thought to share here

"Lets take Su-30MKI's clean RCS as 11.5m2, higher Than a standard Su-27, due to canards & the extra seat."

Just sharing some info
Fact 1

FYI Canards/Fore planes were added to MKI to add stability as its radar is too heavy or MKI is nose heavy. Drawbacks of canards poor radar cross section for MKI vs MKK. Su-35 radar is lighter and advance thus no need for it.
Source Combat Aircraft magazine , Su-35 article

Fact 2

R-77 / RVV-AE has max 80km range in frontal attack against non maneuvering target like big jumbo etc and 15km from rear. It drops to 50km max for fighter type maneuvering target which is (i think I read some where in-spite of Astra) far less than AIM 120 C or SD-10A for fighter type target. That is the reason for RVV-SD now being offered. SD-10A had dual; thrust motor vs single thrust R-77. This is the reason IAF just published RFP for new BVR AAM. Its also influenced by new Chinese BVR such as PL-21

Incorrect.
The Canards on the MKI are there to offset the high positive AOA instability built into the design.
The CG on the MKI is to the rear thanks to the TVC.. and intentionally.
The Su-33 also uses the canards for a similar purpose... to maintain a higher AOA at low speeds.

It is from here: rafale irst | irst system | west germans | 1990 | 2730 | Flight Archive

Interesting how these radars (or any equipment for that matter) is advertised and marketed qouting IDEAL conditions. Battlefields are a different animal the the missile and radar performances are a lot less than what we discuss here. Helps explain the US still ivesting in the F-18 Growler.

As early as 2008 (same year announced the development of the SABR), Northrop Grumman won a prize for the development of T / R modules GaN:

The "future" AESA radars RBE2 and CAESAR (Rafale and Typhoon respectively) used T / R modules GaN, with that demonstrated that the change in the antenna is part of the development of current radar

Although the APG-81 F-35 began development in 2005, "it says" you would use T / R modules GaN, and thus having all according to the manufacturer, significant improvements over previous designs (including the APG -80):

Grifo airborne radars

The P2800 is part of a series of airborne, multimode fire control radars in development by FIAR. The radar family ranges in size and capability from the P2801 Grifetto to the Grifo-M. Most share a common antenna and steering servomechanism, use a magnetron-based transmitter, and have a common data processor core. FIAR claims that all Grifo radars have good Electronic Counter Countermeasure (ECCM) qualities because of their wide-band frequency agility and low sidelobes. The radars are built in three Line Replaceable Units (LRUs): antenna, transmitter, and receiver/processor.

The smallest radar is the P2801 Griffetto or Grifo ASV (Anti-Surface Vessel) that was proposed for the anti-ship version of the Italian-Brazilian AMX attack aircraft. The multi-modal P2801 shows its best performance in the air-to-sea modes. It can use Track-While-Scan (TWS ) against seaborne targets and single-target tracking as well as air-to-ground ranging, ground mapping, terrain avoidance, freeze, beacon, air-to-air search and track, and air combat modes. The P2801 uses a magnetron operating at a low Pulse Repetition Frequency (PRF) to drive a flat-plate, monopulse antenna. A frigate-sized ship showing a radar cross-section of 10,764 sq ft (1,000 sq m) is claimed to be detectable at ranges greater than 55 nm (63 mi; 102 km). FIAR claims that in the air-to-air mode aircraft can be detected up to 22.4 mi (36 km).

The P2803 Grifo-X is a larger system designed for light attack aircraft that shares the same system connectors with the Grifo ASV. The Grifo-X is a fully coherent, pulse-Doppler radar with the same multi-modal flexibility as the Grifo ASV , but possessing better look-up range and offering a limited look- down capability as well.

The P2800 Grifo-M is larger than the Grifo-X and uses a more elaborate multi- processor fire control system. It is designed to fit in the radar bay of a Mirage III or Mirage V interceptor-strike aircraft as an upgrade option. It is still more powerful than the Grifo-X with greater look-down range and discrimination through the use of Fast-Fourier-Transform (FFT ) Doppler- filtering techniques. Two versions are being developed: the Grifo-M for Mirage-series aircraft, using a circular flat-plate array, and the P2804 Grifo-F, a reconfigured system with an ellipitical scanner that fits in the antenna bay of a Northrop F-5E aircraft. Pakistan has ordered the Grifo-M for its Mirage III fleet, with an option for 50 more systems. Singapore has also selected the P2804 for retrofit into its F-5 fleet.

A more recent version of Grifo, the Grifo-7 designed for installation into the Chinese built F-7 (MiG-21) is now being offered. Pakistan has ordered 100 units for installation into its F-7 force. Grifo-7 radar had four major sub-assemblies--antenna, receiver, processor and transmitter - which were being produced at KARF from completely knocked-down and semi-knocked-down kits and shop and line replaceable units, he added. The radar, he said has a coherent fire control system designed to enhance the air-to-air and air-to-ground performance of F-7P aircraft. He said that the pilot production of Grifo-7 radar was now in progress and would soon be followed by serial production to equip the entire F-7 fleet .

STATUS
Development and flight testing completed by FIAR SpA of Milan . Grifo ASV is installed on the Italian AMX trainer and light attack aircraft. First flight of the P2801 was in September 1989 in the nose of Piaggio-Douglas PD808 testbed. The Grifo ASV began full flight testing on a PD808 in January 1990. Grifo-7 is currently under production in Pakistan at KARF for its F-7P fighters.

According to Air Commodore Salim Akbar, Managing Director, Kamra Avionics and Radar Factory, said that his factory had successfully produced the first Grifo-7 airborne radar in October 2000 and was at present installed at an F-7P aircraft for exhaustive operational tests and trials.

KARF's 'Facility for Airborne Radar' has bright future and it would not only meet the existing F-7P requirements but would also produce airborne radar for future PAF aircraft, he added. The radar is a joint venture of an Italian firm FIAR and KARF. The production equipment used to produce Grifo-7 radar is generic in nature and can also be utilised for production of other electronics, avionics related systems, Commodore Salim Akbar replied to a questioner. Lovenzo Fiori, Chief of FIAR Radar Programme, said that during 1990s, his company started to develop its own radar, which was now a family of Grifo radar. The co-production of the Gripo-7 in Pakistan was not only a remarkable success for PAF and KARF but also a matter of pride for FIAR, he added.
