From page 33...
... This section evaluates those features of the antenna's control system that assure that the main beam is never directed below 3° elevation and therefore that points of public access are not exposed to energy other than that from sidelobes. Primary control of the pulse-by-pulse operation of the PAVE PAWS radar resides in a CYBER-l74 computer^ The basic functions performed are to schedule radar pulses, to process data returned from the received echoes, to detect, track, and classify targets, to determine launch and impact points, to operate displays and alarms and to maintain checks on status and operability of the radar and computer.
From page 34...
... .These tests of the beam steering unit also detect malfunctions that could distort the beam severely, therefore protecting the integrity of the beam quite independently of the periodic subarray tests described in Section 4. In this section the panel has so far discussed features of the pointing and control of the transmitting beam that en,sure that areas outside of the desired zone of coverage are not illuminated.
From page 35...
... Instructions can be entered manually into the radar controller, directing the beam to "spotlight" in a chosen direction. Such, manual steering is used for test purposes and for special search operationsBeam steering orders from this manual source are tested in the radar controller for compliance with scan limits.
From page 36...
... Testing of the software for PAVE PAWS during the process of development includes testing of the computer systems against a radar simulator that can simulate, from the point of view of the computer, an actual tactical environment. The tests used include traffic loads (number of targets)
