Title: Matched filter target acquisition radiometric system

Abstract: The matched filter target acquisition radiometric system employs a composite scanning system in searching, acquiring, and tracking relatively small targets on a background of large-magnitude, widely-fluctuating-noise generating terrain. Search for a target is accomplished by a combined circular and conical scan antenna system that generates characteristic invariant wave forms when the circularly symmetric antenna pattern sweeps across a target, patterns that are readily recognized by a matched filter signal processing system, thereupon shifting operation of the antenna control system to a conical scan automatic tracking mode.
