Weapon Locating Radars (WLR) that can track artillery rounds, rockets, mortar shells and unguided rockets, have been developed by NATO, China and India

Weapon Locating Radars (WLR) are primarily used to detect and locate enemy Artillery units by tracking the trajectory of incoming rounds. They can also provide fire correction of friendly artillery units. WLRs usually can also track mortar shells and unguided rockets. Some WLRs also have limited missile tracking and Air Defence capabilities.
