Abstract

This paper proposed an improved method based on fractional Fourier transform (FRFT) for multicarrier LFM signals of MIMO radar (MIMO-LFM) by analyzing its characteristics. First, the intercepted signal model and FRFT are analyzed. Then the signal detection and parameter estimation of MIMO-LFM signals based on FRFT autocorrelation envelope is derived after analyzing the superiority and shortage of conventional FRFT. After that, the detection performance of the proposed method is deduced, and the theoretical results show that this method outperformance the conventional time-frequency method for MIMO-LFM signals processing. Finally, the simulation results demonstrate the validity of the proposed method.
