Abstract:

Quadratic phase function applies estimate of instant frequency to LFM signal.This paper analyses multi-component LFM signal,adopts IQPF to solve the cross terms problem,and uses Clean method for the separation of different strength LFM signals and its parameters estimate,which inhibits the sheltering and interference of strong component signal to weak.The simulation shows that this method is effective.

Key words: LFM signal;QPF;separation;parameters estimate
