you are the OP of the thread right
now lets talk about the topic and that is what is the actual range of current radar on LCA Tejas MK1 well it has a hybrid EL/M-2032(latest version) which has capacity to track a 2m2 RCS target in access of 85 KM and 150Km+ for a 5m2 RCS target cause it has more power and a new quartz rodome which automaticaly increases it range over the legacy composite rodomes
so in short even Tejas in its MK1 non FOC format is more potent than anything your nation has barring F-16 Blk52( for FOC tejas needs IFR probe & OBOGS which Mig21 still doesnt have which its saklted to replace )
as Tejas is already tested under all allitutudes and day&night conditions with its current radar , EW suites , DASH HMDS , Python5-R73-Derby-I Derby ER combo , lightning 3 G3 LDP & all kinds of dump, PGMs, LGBs, Smart extended stand off range mions like Spike250 & there are couple of AESA radars in testing one is Indian made LRDE UTTAM the other one bieng EL-2052 AESA
cheers mate
and OP the fact is non retractable IFR probe is not good for fighter jets as it increases RCS and Drag and also genrates a lot of heat signature if you know anything about aerodynamicks
