| Abstract: | Based on a joint time-frequency two dimensional processing, method for the detection and imaging of moving targets with SAR by using Wigner-Ville Distribution(WVD) is proposed. A parameter estimation method to produce a high resolution image is given. The problems of WVD in dealing with multi-point targets and extent targets are also discussed. The computer simulation results illustrate its availability. |
