There are many difficulties in detecting weak targets from actually measured radar echo. In this paper, we present a feasible approach for weak moving target detection based on the mode decomposition algorithms. First, the EMD algorithm combined with the all-phase FFT was utilized to extract the features of weak moving targets for detection and classification. Considering the defects of EMD, the variational mode decomposition (VMD) algorithm substituted for EMD, which is a generation of the self-adaptive Wiener filter, to realize classification and detection of weak moving targets. The proposed method has good robustness to noise. Simultaneously, we gave the detection results of measured radar signals for experimental verification.
