Abstract

Based on RAT model method, the fast algorithm of parameter estimation of discrete digital signal is studied in this paper. The model of multi-component LFM signal and the parameter estimation of RAT are presented. The fast algorithm of RAT model method of the discrete digital signal is offered, and residual expansion coefficient(REC) is proposed to testify the performance of parameter estimation, and computation cost is analyzed. Simulation results have validated the algorithm of RAT model method has reached the Cramer-Rao bound on both high and low SNR, and meanwhile the validity of the performance analysis of LFM parameter estimation based on REC method is testified. The method presents good application foreground to analyze multi-component LFM signal.
