Initially designed as a standalone system, Rajendra is now equipped with the ability to integrate with a network of sensors, including long and medium-range surveillance radars of foreign and domestic origin.
Rajendra radar uses phase shifters integrated in large numbers for electronic beam steering.
The phase shifter was designed and developed by Prof Bharati Bhat, a scientist from Centre for Applied Research in Electronics (CARE) of IIT, Delhi, and her team.
For those BSR tracks, which are not being reported by Rajendra though under its coverage, target acquisition is initiated with elevation search in the designated direction.
The antenna is skewed in the direction of threat to acquire the targets, which are outside the covered air space.
In 2007, the Akash system cleared the Indian Air Force's user trials with the Rajendra tracking and engaging several targets with warhead equipped missiles.
Prior to that, the Akash system elements, including the Rajendra underwent mobility trials at Pokhran and the radar successfully demonstrated its performance in an EW environment, and its ECCM features at the IAF Electronic warfare range at Gwalior.
[4] 4 Akash batteries make up a group in the Indian Army configuration, with a central 3D CAR radar acting as the early warning sensor for the entire group.In 2007, the Indian Air Force ordered 2 Akash squadrons to begin with.
Many more orders are expected to come over time, as the Indian Air Force phases out its older Pechora systems.
The Phased array antenna is fabricated at Bharat Electronics Limited (BEL), Ghaziabad.
In June 2008, the WLR was accepted for induction by the Army, and 28 units are being produced by Bharat Electronics Limited (BEL).
