Abstract :
A new method of anti-reverberation based on the FRFT is presented. With actual reverberation data and the LFM pulse for separation, good results are obtained: the reverberation is removed largely; and better performance relatively under lower SRR. Based on theoretical analyses and simulation results, two schemes for detecting targets are provided.
