Adaptive Techniques in Radar Signal Processing

Abstract

Adaptive Techniques have come to stay in modern radar systems. From the simpler CFAR and the SLC devices of the last decade, attempts are now being made to incorporate full space-time adaptivity. This paper reviews the most important contributions made in the last decade in this area and their possible repurcussions in future radar system design. Though partial adaptivity making use of the theoretical results are already being contemplated in such areas as Airborne MTI, or in adaptive MTI against weather clutter, the full impact of the adaptive techniqees will have to await further developments in the areas of convergence rate, solid state T-R modules upto X-Band and VLSI devices for processors.
