摘要

本文提供了一种“半确定性”描述，实现了太赫兹波段具有粗糙边界的大型复杂目标相干和非相干散射的快速仿真。结合生成逆合成孔径雷达(ISAR)图像的射线管积分公式，提出了一种利用射击和弹跳射线(SBR)法在任意纵横角下获得粗糙边界目标的大量ISAR图像的快速仿真方法。

Fast ISAR Image Simulation of Targets with Rough Boundary at Terahertz Frequencies

This paper provides a "semi-deterministic" description to realize fast simulation of the coherent and incoherent scattering of electrically large complex targets with rough boundary at THz bands. Combining with a ray-tube integration formula to generate inverse synthetic aperture radar (ISAR) images, a fast simulation method is presented to get large collection of ISAR patches of targets with rough boundary at arbitrary aspect angles by using the shooting and bouncing ray (SBR) method.
