Abstract

Radar cross section(RCS), extrapolated from small angle rotation in high frequency band by the traditional inverse synthetic aperture radar(ISAR) imaging, can not be presented full aspect measurement. In order to address this problem, we propose ultra-band large angle rotation method to derive RCS from ISAR imaging. This method analyze the distribution characteristic with small angle rotation between radial range and cross range as well as illuminate the point spread function(PSF) of target scattering distribution mechanism under measurement and imaging condition. Experiment show that this method not only can be strengthen the scattering position image of target, but also enhance the RCS resolution.
