Multi-component High-Rrder FM Signal Estimation and Suppression Based on Radon-MPF-ambiguity Transform

This paper focuses on the situation that the performance of receivers will greatly degrade when Multi-component high-order FM Signal exists. We present a method to estimate and suppress the Multi-component high-end FM Signal based on Radon-MPF-Ambiguity transform. It helps estimating the parameter of the high order FM signal with less calculation. Then, suppress the interference one by one through adjusting center frequency of heterodyne filter. Numerical experiments show that the algorithm can effectively estimate and suppress the multi-component interference signals.
