Swathi

Swathi Weapon Locating Radar (WLR) is operating in C-Band battle field radar that automatically locates hostile artillery, mortars and rocket launchers and tracks friendly fire to locate the impact point of friendly artillery fire to issue necessary corrections. The radar is designed to detect projectiles with small cross section across the battle space horizon, and has the capability to handle simultaneous fire from weapons deployed at multiple locations.

Swathi (WLR) is coherent, electronically scanned phased array radar using intrapulse bi-phase modulation (Barker codes). A polyphase modulation is optional possible (Frank Code). The transmitter uses a traveling wave tube (TWT) as power amplifier.
