Counter-battery radar

A counter-battery radar (alternatively Weapon Tracking Radar or Target Acquisition Radar) is a mobile radar system that detects artillery projectiles fired by one or more guns, howitzers, mortars or rocket launchers and, from their trajectories, locates the position on the ground of the weapon that fired it. More advanced systems can electronically send aiming instructions to friendly artillery for firing at hostile targets with counter-battery fire. Some radars like the AN/TPQ-37 or the COBRA can calculate where hostile projectiles will land. Modern counter-battery radar can locate hostile batteries up to about 50 km away depending on the radar's capabilities and the terrain and weather. A counter-battery radar is attached to an artillery battery or their support group.
