Abstract:
Aiming at the problems of low accuracy and high computation complexity when estimating multi-target movement parameters, an improved method combining time-frequency reassigned smoothed pseudo Wigner-Ville distribution and Radon( RSPWVD-Radon) transform is presented. This method adopts the constant false alarm rate detection and thresholds processing to estimate multi-target acceleration and velocity parameters in LFMCW radar, and can overcome the shortcomings of heavy computation burden and error accumulation effect in the existed algorithms. The realization steps of estimation algorithm are provided. The simulation results show that the method has higher parameter estimation accuracy even when the signal-to-noise ratio( SNR) is lower.
