Abstract
This paper studies the technology of the correlative dechirp,and analyzes its existing shortcomings.Some differences between Wigner-Ville method and ambiguity function are compared when they are used to analyze the LFM signal.A new algorithm of using RAT transform and fast dechirp is proposed by comparing the difference.Finally we validate the effectiveness of the algorithm through computer simulation.This method solves the shortage of the correlative dechirp and decreases the high computation of the RWT method.It can also solve the problem that the pure RAT method can only estimate the frequency modulation rate.关键词
