Abstract :
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.
