Abstract :
Radar illumination of a rotating object normally yields a modulation of the backscattered signal. Here we analyze this modulation phenomenon of the periodic moving objects in general, and present the modulation feature extraction methods to identify the number of modulation sources in detail. Finally, we verify the presented method with the measured and simulated data
