  • Based on the fact that linear frequency-modulated (LFM) signal has a good focusing property in fractional Fourier transform(FRFT) domain, a moving target detection method in the presence of reverberation is presented using FRFT combined with fourth-order mixed cumulant slice (FRFT-FOMCS). Some details for designing the FOMCS based on FRFT are discussed. The present FRFT-FOMCS algorithm is more suitable for detecting LFM signals than the FRFT algorithm. Simulation results show that the FRFT-FOMCS algorithm can effectively detect and identify high speed moving target echo in reverberation.
