The radar scans a 90-degree sector for incoming rocket, artillery and mortar fire. Upon detecting a possible incoming round, the system verifies the contact before initiating a track sequence, continuing to search for new targets. The incoming round/rocket is tracked during its initial upward/launch trajectory (i.e., the linear portion of its flight path) prior to reaching apogee. A computer program analyzes the track data and then extrapolates the round\u2019s point of origin. This calculated point of origin is then reported to the operator with map coordinates, thus allowing friendly artillery to direct counterbattery fire towards the enemy artillery. The system has a reported range of up to 50 kilometers. The system may also be operated in a friendly fire mode to determine the accuracy of counterbattery return fire."@en . . . . . . .
