Abstract:
The patent relates to adaptive thresholding to enhance target detections in the presence of clutter. A closed loop feedback system functions to maintain an average constant false alarm probability within three range intervals. Radar video signals are sampled, then compared with a thresholding signal comprised of a constant plus the feedback signal. Average constant false alarm probability is maintained by forcing the signal to a constant duty factor by use of pulse stretching. The feedback signal is filtered over the range intervals to adjust for range variations in clutter density.
