摘要

针对ISAR成像中传统插值算法计算量大的问题，提出了一种沿雷达瞄准线插值的方法。根据大旋转角度的几何模型，对坐标变换引起的方位畸变进行重采样。仿真结果表明了该算法相对于传统插值算法的优越性。

A polar format imaging algorithm applied to ISAR with large turning angle

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.
