The Indian Swathi radar was selected by Armenia following a tender, in which similar radars of Russian and Polish production also took part. The Swathi WLR radar has a headlight operating in the C-band and provides fast and accurate automatic location of enemy fire weapons, can operate simultaneously with several (up to seven) shells fired from different types of weapons and from different directions. The target range depends on artillery caliber and is stated for up to 40 km.
Earlier last year in 2020 India had won a $40 million deal to supply four Made In India Swathi Weapon Locating Radars (WLRs) to Armenia after India outbid similar offerings by Russia and Poland to win the deal. In March 2020, India and Armenia signed a deal for the sale of four Swathi weapon locating radar (WLR) stations. Bharat Electronics Limited (BEL) which manufactures the Swathi Weapon Locating Radars (WLRs) has now started deliveries of them.
SWATHI weapons locating radars is an electronically scanned phased array radar that provide fast, automatic, and accurate locations of enemy weapons like mortars, shells, and rockets in its 40-km range (Upgraded version has range of 50 KM). SWATHI, developed by India’s premier R&D organization, Defence Research and Development Organisation DRDO’s Electronics and Radar Development Establishment (LRDE), can simultaneously handle multiples projectiles fired from different weapons at different locations.
The system is capable of adjusting the fire of our own artillery weapon also. The SWATHI radar can detect weapons that includes 81mm or higher calibre mortars, 105mm or higher calibre shells, and 120mm or higher calibre free flying rockets.
