Paper Abstract

A particular method of detecting unresolved targets using simulated monopulse radar data is examined in detail. The system is assumed to be correctly calibrated i.e. the decision boundary is calculated based on the true values governing the hypothesis that only a single target is present in the range cell. The system performance is analyzed under varying values for target ranges, angles between the beam pointing direction and the actual off-boresight angle of the targets, waveform power and number of pulses. It is shown that these parameters have a pronounced impact on the Boundary, Metric and Decision Surfaces. The False Alarm probability for a single target as a function of waveform power is considered, as also are the detection probabilities when two targets are present. The important issue of locating the decision point on the Boundary Surface is briefly discussed.
