sar-synthetic-aperture-radar's Introduction

SAR, Synthetic Aperture Radar 合成孔径雷达

这是我在研究生期间学习 SAR/InSAR/PolSAR 等相关领域时编写的Matlab代码(仿真、实验)以及一些总结。毕业后已经离开这个领域了,所以也不会再有新东西更新了(更新到此结束),哈哈哈。

记得之前读研时,网上这个领域的开源代码和材料等是很少的(论文倒是不少。不过SAR这个领域本身就挺小众,而且个人感觉入门门槛还是比较高的),什么东西都要自己一点点摸索。所以我把读研期间的一些东西整理并分享出来,如果能有一点参考价值,也就是这个项目的意义了。

  1. 关于 SAR 成像算法的学习和仿真,主要是两个经典算法,距离多普勒算法即 RD 算法,chirp scaling算法即 CS 算法;仿真包括点目标仿真,以及对Radarsat-1数据的成像处理。简略版本可见仓库:https://github.com/denkywu/Simulation-of-SAR-Imaging-Algorithm (仅给出了RD和CS算法的代码)。本仓库中进行了分类,给出了一些实验报告和总结;
  2. 关于 InSAR 即干涉SAR的学习和仿真。主要是自己仿真了(生成回波原始数据并进行成像和干涉处理)两个场景,一个是平地场景,一个是圆锥场景。简略版本可见仓库:https://github.com/denkywu/InSAR-Simulation-and-Studies 。本仓库中进行了分类,给出了一些实验报告和总结;
  3. 关于 PolSAR 即极化SAR,我做的工作主要是极化定标。详见仓库:https://github.com/denkywu/PolSAR-Calibration 。由于极化处理中涉及到过多的实际数据处理和分析,不便于分享,所以也没有更多内容了。

由于本人水平有限,文中不免有错误,还望各位海涵。

谢谢!
