New Non-Linear FM Pulse-Compression Technique for Radar Applications

Abstract

The development of pulsed type radar signals is examined, with a brief review of matched filtering. Gated RF, linear and nonlinear FM pulse- compression (chirp) and matched filtering of radar signals is reviewed in depth. Emphasis is given to identifying the desirable properties of each method. A new method of non-linear FM pulse-compression is introduced; it utilizes the Eigen Function (a form of the raised-cosine family of functions) as its modulating term. Its properties are then compared to those of the linear and nonlinear systems reviewed in the preceding sections. Design considerations for implementations on a surface acoustic wave device are presented.
