Title: Range and angle discriminator for leading edge radar tracking

Abstract: The disclosed invention provides an accurate, simple and flexible method processing the receiver output of a high range resolution monopulse tracking radar to generate range and angle tracking error voltages based on the location of only the leading edge of the target echo replacing the conventional analog range error detectors and angle error processors in closed tracking loop systems. The invention also processes the radar return signal to avoid interference from repeater jammers or multipath returns at low angle tracking.
