摘要

Aiming at the problem of large computation of traditional interpolation algorithm in ISAR imaging, a method of interpolation along radar line of sight is proposed. According to the geometric model of large rotation angle, the azimuth distortion caused by coordinate transformation is re-sampled. The simulation results show the superiority of this algorithm over other traditional interpolation algorithms.
