he chief utility of this type of radar is to detect and track multiple types of incoming ordnance of any calibre greater than 23 mm (a radar cross section of 0.001 m2 ) and project their impact points. After identifying the number, size, trajectory and point of impact of any ordnance fired, the onboard computer's ballistic computation module is then able to backplot the trajectory and achieve a fix on the opposing forces' firing position. "This allows any units being protected by the WLR-100 to transmit those co-ordinates to close air support aircraft or their own artillery," one of the PIT designers told Jane's . "The accuracy of the system for identifying both the impact point of the ordnance in flight and the point of origin is better than 1 per cent."
