Blind splitting solution of Doppler spectrum for synthetic aperture radar

Due to the width spread and center shifting of the Doppler spectrum, the spectrum splitting phenomena may be drawn in synthetic aperture radar. Based on a proposed double threshold processing, a novel method of blind spectrum splitting is developed. Via a single range unit sampling, the proposed method may correctly realize spectrum splitting without any other auxiliary information. Lastly, simulation experiments and real data are also provided to validate the proposed method.
