Jaguar fighters getting new generation missiles; IAF approaches industry to modify two planes as pilot project​


The latest upgrade, DARIN-III, which commenced recently, includes a new cockpit layout with dual multi-function display, new synthetic aperture radar with a range of 250 kms for surface targets and 150 kms for aerial targets, enhanced electronic countermeasures, new fire control radar, inertial navigation system with terrain mapping and geodetic height correction system and an engine and flight instrument system.

This actually looks reasonable for ground/surface attack purpose and limited air to air combat. Unless Indian tried to use Jaguar as air superiority, then there will be problem.

The information on the tweet is quite generous including the TRM counts, peak power and beamwidth. It's easily gleaned the radar operates at high end of X-band at 11 GHz and the range figure provided looks reasonable, 150 km is for very large targets in order of 10 sqm. Range for smaller targets like 3 sqm is smaller about 110 km for probability of detection of 50% while for 90% where lock on or engagement with missile could be allowed is 80 km. While range for surface target should refer to ship target with RCS of maybe 1000 sqm+.

It's basically a 21st century Agave radar.

At least if it can give them the chance to turn tail while detecting fighter ahead before getting hurt it's nice. It's a ground attack aircraft afterall.
