探月雷达是一个重要的月球探测方法，理论基础都是利用频率在1MHz—10GHz之间的电磁波进行探测，不仅能够实现月表巡视探测，同时也能实现轨道卫星探测。通过对前人研究成果总结，在随机等效介质的理论基础上，建立符合月球浅表实际情况的三维介质模型，通过大型模型的电磁响应计算，获得月表介质不同条件下电磁响应的变化规律，进而分析电磁的极化方式的响应特征，提高探测的效果。研究基于全波反演和随机反演算法，利用探月雷达数据反演月球浅表界面特征、岩石组分。在多域计算方法基础上，将轨道探月雷达数据和月表探月雷达数据有机结合起来，通过月表高精度、高分辨率探测信号对轨道雷达数据进行标定和校正，实现月表多尺度探月数据的解释和资源评价。通过项目的研究，对探月雷达的理论成果进行总结，也为进一步的探月和深空探测提供重要的方法技术。

Lunar radar method is an important method in lunar subsurface medium detection, which use the electromagnetic wave with frequency range between 1MHz-10GHz to sound the discontinue layer in soil and rock. This method can be applied by satellite detection and surface detection. We will summarize the results conducted by former researchers, and build the 3D stochastic medium models, and then calculate the response of the models which can be shown optimistic parameter for the radar system. Also, the full-wave inversion and stochastic inversion algorithms will be developed and applied to obtain discontinue layer and components. The multi-domain FDTD algorithm will be used to simulate the satellite lunar radar and surface lunar radar detection, the results can be applied to calibrate and correct the satellite lunar radar data, and which can be improve the interpretation and evaluate the recourse. This project will provide new theory and technique for lunar and deep-space detection based on the radar method.
