本文报告一种地下目标微波全息成像雷达的可行性研究。这种雷达拟用于城市环境中地下公用设施,诸如供水管道、电缆等的探查。它的主要优点是能提供高分辨力的可视图象,有利于对地下目标的识别。文中给出了成像的理论分析,介绍了实验系统和数据拾取与处理中所遇到的问题及其解决办法。最后给出了实验结果和当前进展的情况,并指出需要继续解决的问题。
This article reports on the feasibility of a ground-based microwave holographic imaging radar. This radar is intended for the exploration of underground utilities in urban environments, such as water pipes, cables and the like. Its main advantage is the ability to provide high-resolution visual images that facilitate the identification of underground targets. The paper gives the theoretical analysis of imaging, introduces the problems encountered in the experimental system and data acquisition and processing and its solutions. Finally, the experimental results and the current progress are given, and the problems that need to be solved continue to be pointed out.
