I am going to say something that maybe i shouldn't but to shut some members once and for all...
The actual RCS of JFT is Classified but what i know, it is MUCH less than even the Falcons and goes in mere fractions! To such an extent that during simulated engagements, Falcon pilots were having difficulty to trace it ! The biggest contribution to this is the DSI intake which reduces the RCS to a great extent. About the radar, KLJ-7 is based on RP-35 zhemchug series which itself was specifically made as a high performance, multirole radar for Mig-35. Though still mechanical pulse doppler, it is one hell of a radar that includes technologies from IAFs favorite ELAT 2032 and RP-35s joined by Chinese expertise in electronics and PCB, micro processors. Keep under estimating this fighter folks, it will benefit us. On the topic, MIG-29 versions before the SMT are inferior to JFT in terms of avionics, radar, weapon and sensor fusion. This is a reality that India at the moment DOES NOT have any SMTS and till they do, theirs are inferior to JFT. Bitter pill to swallow for them but i trust my source a lot.
