let me check again
here it is :
According to the pictures released on the scene, this JF-17 Block 3 prototype uses a large number of AVIC's shelf products, and some technologies have been applied to our military's own J-10C and J-20 fighters. From the figure, the most obvious improvement of the JF-17 Block 3 is the replacement of a larger polygon full-frame diffraction head-up display (HUD) and an integrated cockpit display, similar to the J-20 fighter screen display. In addition, the Nine Dragons Block 3 is also equipped with an advanced omnidirectional infrared missile warning system. At present, three new fighter aircrafts of the J-10C, J-16 and J-20 are equipped with this advanced infrared warning system.
According to previous reports from AVIC, the Nine Dragons Block 3 will install Active Phased Array Radar (AESA) according to Pakistan ’s requirements. However, the prototype 3000 did not have a radar, only an aluminum metal cover and counterweight, and a nose radar. The size of the hood did not change significantly.
This may mean that JF-17 Block 3's active phased array radar is still in the bidding process and has not been finalized. At present, two domestic companies are bidding for the radar project of JF-17 Block 3, one is AVIC Thunder and Lightning Institute (607), and the other is China Electric Power Division 14.
14 plans to install a liquid-cooled KLJ-7A active phased array radar for Nine Dragons, while 607 plans to install a new type of air-cooled phased array radar, both of which were displayed at the Zhuhai Air Show. KLJ-7A radar has large power and relatively mature technology, but it needs to redesign the head space; 607 air-cooled phased array radars have low power but low power consumption, and have successfully solved that the equipped PD radar fighter cannot be directly replaced in place. Problems with active phased array radar.
