Weapon Locating Radars Swathi

In News
  • Ministry of Defence, recently signed contracts for procurement of improved Akash Weapon System and 12 Weapon Locating Radars, WLR Swathi (Plains) for the Indian Army at an overall cost of over Rs 9,100 crore.
About Swathi
  • The WLR Swathi has been jointly developed by the Electronics and Radar Development Establishment (LRDE) and Bharat Electronics Limited (BEL).
  • Its main purpose is to detect and track incoming artillery rounds, mortar, and rockets, and locate their launchers.
  • It achieves this through a phased array antenna system that scans the sky, searching for incoming rounds.
  • When the radar detects incoming artillery, it calculates the point of origin for counter-battery fire.
  • The WLR Swathi’s secondary role is to provide fire corrections to counter-battery fire by tracking and observe the fall of shot from friendly guns.
  • It is an indigenously designed WLR which is capable of locating guns, mortars and rockets firing own troops, thereby facilitating their destruction through Counter Bombardment by own firepower resources.
  • This will enable troops to carry out their operational tasks without any interference from the enemy and also provide them safety against enemy fire.
  • Induction is planned to be completed in 24 months.
Features
  • The WLR Swathi has an impressive range, with a detection range of up to 30 km for large caliber artillery rounds and up to 40 km for unguided rockets.
  • It can track up to 7 targets simultaneously and is capable of tracking rounds fired at both low and high angles.
  • The radar array has a maximum scanning sector of 90°, and the scanning sector can be changed in response to threats by rotating the whole array by 135° on either side within 30 seconds.
  • The WLR Swathi can store up to 99 target locations with broad digital map displays.
  • The data-linking feature allows for remote operation and better situational awareness at higher echelons of the command hierarchy.
