Convergence Rate in Adaptive Radar

Abstract

This is the fourth and final quarterly progress report for a one year study of convergence in adaptive radar. During a series of earlier adaptive radar studies at TSC, funded by Naval Air Systems Command, a method of optimizing both the angular and doppler response in AMTI (Airborne Moving Target Indication) radars was described, analyzed, and simulated in some detail. These studies showed that adaptive AMTI radar can provide a major improvement in performance in a mixed clutter/ECM environment. In the first progress report the basic adaptive AMTI technique was described, and three adaptive algorithms were compared. These algorithms were sample matrix inversion SMI, inverse matrix update IMU, and the Applebaum loop algorithm. Both SMI and IMU algorithms are shown to be very fast in terms of number of data samples required for convergence. These algorithms are more complicated than the loop technique, though, and are probably best implemented using digital techniques. This report presents results of a computer simulation of analogue to digital (A/D) conversion.
