SAM Hawk SR (AN/MPQ-51)

The PAR is the primary source of high- to medium-altitude aircraft detection for the battery. The C-band frequency allows the radar to perform in an all-weather environment. The radar incorporates a digital MTI to provide sensitive target detection in high-clutter areas and a staggered pulse repetition rate to minimise the effects of blind speeds. The PAR also includes several ECCM features and uses off the air tuning of the transmitter.

The Hawk system consists of seven major components. Its Information Coordination Central (ICC) and Battery Control Central (BCC) perform critical command and control functions, including automatic data processing, friend or foe identification, and digital voice and data communications. The Pulse Acquisition Radar (PAR) AN/MPQ-51, a search radar with a 20 rpm rotation, for high/medium altitude target detection. Continuous Wave and Pulse Acquisition Radars (CWAR) AN/MPQ-55 provide low-to-medium-altitude target detection, while the High Power Illuminator tracks and illuminates targets (HIPIR) AN/MPQ-48. The Hawk missile performs the target kill function, providing a formidable defense against fixed and rotary wing aircraft, cruise missiles, and short-range tactical ballistic missiles. The launchers, in addition to their missile aiming function, support pre-launch commands and transport the missiles in tactical situations.

A typical HAWK battery consists of 1 PAR radar, 1 CWAR radar, 2 HIPIR radars, one PCP Platoon Command Post, two launcher section controls and six M192 launcher units with 18 missiles.
