The Angle Tracking Computer (ATRAC) for the Experimental Array Radar System.
Abstract
UITSEXPERIMENTAL ARRAY RADAROne of the earliest problems encountered and solved by investigators in the field of radar was that of measuring and presenting the error between the antenna axis and the target. Errors in pointing direction are determined by sensing the angle of arrival of the echo wavefront and correcting the antenna position to keep the target centered in the beam. The principal applications of tracking radars are weapon control and missile range instrumentation. Several techniques have been used to implement angle tracking in radar systems. For example the conical-scan, sequential-lobing, and monopulse (both phase comparison and amplitude comparison) are well known techniques described in the literature. Since the US Army Missile Command's Experimental Array Radar (EAR) System is a phase-monopulse radar, this technique is described in detail in the text of this report. (Modified author abstract)
