    Those looks more like Troposcatter communication system to me.

      Good progress in the WS-19 program (Engine, mainly for J-35/FC-31 and possibly future blocks of JF-17) -

      Benefitted from the design and materials of WS-15 engine, it only took one year to complete the design, took half a year to complete the experimental verification of 1st engine, took one third the time of engine manufacturing compared with before.

            Does anyone have information like what range the klj-7a radar's side arrays can track?


            I thought the fall of western civilization was a tragedy, now I realize it's a comedy.

              IMO, small aperture side arrays with a "smallish" number of TR modules should be able to perform GMTI and surface target track out to 15km in clear weather. Rain reduces the range. It would take several minutes to build the initial SAR map, depending upon the dimensions of the area of interest. Small AOIs significantly reduce the time needed to build a SAR map. That is why you need to cue with ESM which has good pointing performance. 15km is likely well within point defense SAM range, so the small side array is only useful in permissive environments.

                I have found this info here https://twitter.com/dafengcao/status...59531432009729 I do not know if this was added here(I do not pay much attention to China's air force thread) before but the image was take on Nov 2018. It just shocked me they pursued the same thing. They have counted 600 modules on this. Also thanks for your info.
