DOA Estimation of Multi-component LFM Signals Based on the FRFT

摘要：

A novel algorithm for the direction of arrival (DOA) estimation based on the fractional Fourier transform (FRFT) is proposed.Multi-component LFM signals are filtered and demodulated into a number of stationary single frequency signals.Then the direction estimation of LFM signals can be achieved by combining with the traditional MUSIC method in the fractional Fourier (FRF) domain.The statistical analysis is also performed which perfects the method theoretically,simulation results are provided to show the validity of our method.
