Rotating velocity estimation for ISAR targets via Radon detection of lines
Rotating velocity (RV) estimation is a prerequisite for inverse synthetic aperture radar (ISAR) to re-scale the imaging results from the conventional range-Doppler (RD) domain to the range-cross range domain. Based on the mapping of RD imaging, two slope functions, i.e. Doppler-range slope and range-Doppler slope, are defined for a line on the image plane. Then, by detecting the line features on the RD plane with a Radon-CLEAN scheme, this paper proposes a RV estimation method by fitting the slope function of the extracted line features. Key steps for the method are presented and numeric experiments are given to demonstrate the effectiveness of the proposed method.
