PAR coverage. The system can operate in three different modes to include ASR, PAR and
Combined mode. In ASR the azimuth antenna spins at 60 RPMs and used only to process targets typical to any ASR and also utilizes the AN/TPX-56 to process IFF targets. Both raw returns and IFF are processed in the tracker. In PAR mode the azimuth antenna does not spin and fixed normally on the reciprocal runway heading to pickup targets in azimuth and elevation planes to process typical PAR targets. In combined mode the azimuth antenna spins at 60 RPM's to provide the 1 second ICAO update rate to the PAR display. The antenna arrays consist of Trans Receive Modules (TR) modules that are calibrated for phase and power to allow formation of the RF beam in space. The display software has two modes of operation ASR/PAR. The PAR display utilizes ITT software and the ASR software is a derivative of BDM software used at several ranges.

display indicators and one PAR indicator located in the operations shelter, and one each ASR and PAR indicator located in the maintenance shelter. Complete operations are conducted from the operations trailer. The system is limited to a single runway but has the capability of providing opposite direction runway operations with the aid of a transportable turntable.

Earlier radars included the AN-FPN-36 "Quad Radar", a compact and portable system that could function as either an airport surveillance radar, GCA radar, non-precision ASR approach radar, or airport surface detection equipment, and the AN-CPN-4, a larger, more modern and precise system that provided
