摘要

傅里叶变换在ISAR信号和图像处理中得到了广泛的应用。在大多数情况下，ISAR信号在多普勒频谱中表现出时变行为。因此，ISAR信号的联合时频分析(JTFA)更为有用。本文介绍了一种结合CLEAN技术的WVD算法。同时，对ISAR中的LFM信号进行了仿真，比较了它们的性能。结果表明，该算法优于典型的WVD和SPWVD算法。

A New WVD Algorithm Jointed CLEAN Technique in ISAR Imaging

The Fourier transform has been widely used in ISAR signal and image processing. In most cases, ISAR signals exhibit time-varying behavior in the Doppler spectrum. Thus, a joint time-frequency analysis (JTFA) for ISAR signals is more useful. In this paper, we introduce a new WVD algorithm jointed CLEAN technique. Meanwhile, the simulations of LFM signal in ISAR are adapted to compare their performance. It is shown that our algorithm is better than typical WVD and SPWVD algorithms.
