A Method of Improving SCR for Stepped-FM Radar

Abstract

This paper proposes a method of designing a matched filter for stepped-FM radars. The proposed method estimates an autocorrelation function of signals reflected from a target and then derives the matched filter by taking discrete-Fouriertransform of the estimated autocorrelation function. Computer simulation results show that the proposed method outperforms the conventional synthetic bandwidth method in terms of signal-to-clutter ratio.
