The contract is for four Swathi weapon locating radars which provide fast, automatic and accurate location of weapons like mortars, shells and rockets in a 50 km range.
The radar can simultaneously handle multiple projectiles fired from different weapons at different locations. The Indian Army is also using the same radars for its operations along the Line of Control in Jammu and Kashmir.
The Armenians also carried out trials of Russian and Polish systems which were found to be good, but they finally chose the Indian system for acquisition, said sources.
