探地雷达（GPR）是利用高频电磁波来确定介质内部物质分布规律的一种探测雷达。在深空探测领域中，利用星载探地雷达进行星球次表层探测，已经成为了解星球次表层结构的重要途径。但是，由于卫星运行速度的影响，使得星载探地雷达的成像具有多普勒效应，与静止平台下的成像有很大不同。欧洲航天局（ESA）与美国航天局（NASA）都已经利用星载探地雷达对火星进行了成功探测，但在国内该方面的研究还不多，尚处于起步阶段。本文从一般探地雷达与星载探地雷达的成像区别入手，在两种背景下对分层介质的探测进行了成像算法研究与回波仿真模拟，并对结果进行了解释和分析。本文的结论也可以用于机载平台等其它运动平台的情况。

Ground-penetration Radar（GPR） is a kind of detection radar using high frequency electromagnetic waves to determine the distribution of the internal structure of the material. In the field of deep space exploration, the utilization of space borne GPR to explore the subsurface structure of the planet has become a important way to understand the planet. However, due to the velocity of the satellite, the space borne GPR has a Doppler effect in its images, much different with images imaging by the static GPR. European Space Agency （ESA） and National Aeronautics and Space Administration （NASA） have been using space borne GPR to explore Mars successfully. However, related researches in China are few, still on the initial stage. In this paper, we will begin with the discussion of the differences between the imaging method of the general GPR and the space borne GPR. Then the imaging method and echo simulation in both fields and the interpretation and analysis of the echo simulation will also be discussed. These conclusions can also be used for airborne platforms and other motion platform situations.
