In the early version, the AN/MPQ-46 High Power Illuminator Radar (HiPIR) had only two round antennas, one for transmitting and one for receiving. The HiPIR can detect and automatically accompany individual assigned targets in azimuth, elevation, and distance.

About 1983, in phase 2 of the modernization of the Fla missile complex “Hawk”, the High Power Illuminator Radar received an optical-visual component called Tracking Adjunct System (TAS). This camera is located between the two reflectors of the HiPIR. This modernization has already significantly improved the EPM properties.

The decisive improvement, however, came in phase 3 (about 1995) with the introduction of the Low Altitude Simultaneous HAWK Engagement (LASHE) system and a compensation antenna with a wide aperture angle, which offers more possibilities for action against saturation of the receiving channel and thus increases the probability of detecting low-flying targets (rectangular antenna next to the round reflectors).
