| Abstract: | The modern signal processing methods used on radar for detecting cluster targets are analyzed,and the merits and defects of them are investigated.Some modern radar signal processing methods,such as Wigner-Ville Distribution,Short-Time Fourier Transform(STFT) and Wavelet Transform(WT),are analyzed.Some modified methods are put forward,which are used to modify the defects of the modern signal processing methods.WT is a time/frequency domain analysis method with multi-target detection capability,which can compensate for the limitation of STFT perfectly and has found more and more application in radar signal processing.The detection effects of these methods are analyzed and the direction for further study is indicated.This paper emphasizes on theoretical analysis.The main purpose is to make some provisions for deep research on multi-target detection. |
