One HPIR High Power Illuminating Radar: The early AN/MPQ-46 High Power Illuminator (HPIR) radars had only the two large dish-type antennas side by side, one to transmit and one to receive. The HPIR automatically acquires and tracks designated targets in azimuth, elevation and range. It also serves as an interface unit supplying azimuth and elevation launch angles computed by the Automatic Data Processor (ADP) in the Information Coordination Centre (ICC) to the IBCC or the Improved Platoon Command Post (IPCP) for up to three launchers.
