摘要：

合成孔径雷达(SAR)卫星的出现为获取地球空间信息提供了重要手段，本文研究的即是SAR卫星成像任务规划问题。首先描述了SAR成像卫星的一般工作流程，说明针对可见光卫星进行成像任务规划的方法不再适用于SAR成像卫星任务规划；然后归纳了影响SAR卫星成像的主要约束。在此基础上，提出了双层插入规划(DHIP)方法，该方法将待规划任务在星载SAR开关机信息元组级和成像信息元组级两个层级上逐次进行试探性插入，采用边构造边检测的方法获得该问题的优化解。实验结果表明，该方法计算速度快，可以有效解决SAR卫星成像任务规划问题。

Abstract:

The emergence of earth observing satellite with Synthetic Aperture Radar (SAR) onboard provides a significant instrument to obtain geospace information. This paper studies rightly on the SAR satellite imaging planning problem. Firstly, the general imaging process of SAR satellite is described to illustrate that the methods pertinent to optical satellite imaging planning are no longer suitable for the problem of a SAR satellite imaging planning.Secondly, the main influential constraints of SAR satellite are induced. Based on that, an approach called DHIP (Double Hierarchy Insert Planning) is proposed and described detailedly. The main idea of this method is to form an optimized scheme by tentatively inserting every candidate imaging request through two hierarchies, which are the hierarchy of SAR opening and closing, and that of photographing, by a checking while constructing method. The final experimental results show that the DHIP algorithm works fast and is able to get a satisfying scheme under general circumstances.
