本文基于联合时间频率二维分布的研究方法,探讨了WVD(Wigner-Ville Distribution)变换用于合成孔径雷达运动目标检测和成象的可行性,给出了能得到运动目标精细成象的参数估计方法,并对多点目标和面目标情况下WVD存在的问题进行了研究。计算机模拟验证了算法的有效性。
In this paper, we discuss the feasibility of using WVD (Wigner-Ville Distribution) transform for the detection and imaging of moving targets in synthetic aperture radar (SAR) based on the method of joint two-dimensional distribution of time and frequency. The parameter estimation Method, and studies the problems existing in WVD under multi-target and surface target conditions. Computer simulation verifies the effectiveness of the algorithm.
