India’s defence research and development organization (DRDO) is exploring the development of “Active Electronically Scanned Array Radar (AESAR)” developed by Electronics and Radar Development Establishment (LRDE) for the HAL Tejas program also now for other combat aircraft of Indian Air Force, which includes new configuration for use on Sukhoi Su-30MKI twinjet multirole air superiority fighter developed by Russia’s Sukhoi and built under licence by India’s Hindustan Aeronautics Limited for the Indian Air Force.

Industrial sources close to have informed that the proposal is still at the discussion stage since the indigenous Active phased array technology for fighter aircraft is still in the developmental and trials stage but the program has made recent progress and already has undergone installation process on LCA Tejas LSP-2 which has been deputed to carry out flight trials and integration of India’s indigenous AESA radar.

DRDO Chief in his recent interview confirmed that indigenous AESA fire control Radar will be available for 83 Tejas Mk1A to be produced by HAL even though Elta EL/M-2052 AESA FCR has been ordered by HAL for the entire fleet. AESAR has over 16 different types of operational modes and several of the basic modes have been cleared in rooftop trials and on the leased business jet which was used before the Radar was integrated into LCA-Tejas, several more modes will be tested and cleared before final production model is ready in next few months.

LRDE already has manufactured 4-6 developmental models of AESAR FCR for testing and trials and in its present configuration can track 100 targets simultaneously and engage 6 of them. It has a scan range of 150 km against 2m2 RCS aircraft. With 736 TRMs, AESAR FCR can be upgraded with larger TRMs for bigger aircraft as long as aircraft can generate enough power required for the FCR said official close to the program.

AESAR FCR if not ready in time for Tejas Mk1A program surely will be used for Tejas AF Mk 2 MWF which is an enhanced version of the Tejas Light Combat Aircraft (LCA), with modifications comprising a slightly longer length and better payload. LRDE is already working on the development of Next Generation AESA technology which will be used on India’s 5th Generation AMCA fighter jet program. was told that LRDE already has asked Interested Indian industrial companies to apply for four licenses which it is offering of its Active phased array technology which can be used to develop for differently configured radars for different planes and other aerial platforms. LRDE is confident that AESAR FCR can be configured to be used on any aircraft and the AESAR FCR can be configured as per and aircraft, scaled and powerful version for bigger aircraft and smaller variant like that for LCA Class fighter aircraft.

India’s Bharat Electronics Limited (BEL) is already developing the next generation infrared image search and track system (IRST) for Sukhoi Su-30 MKI aircraft so that it can be used to detect stealthy aircraft development of indigenous AESAR FCR will allow India much better integration platform for locally developed weapons systems but proposal is still at the advance stage of discussion and still in the proposal stage.
