摘　　要：针对典型土壤微波辐射特性,分析了传统的测量方法。研究了微波辐射干涉直接采用测量原理,建立了基于压缩感知的土壤湿度微波辐射图像重构系统。利用该模型获取可信、高分辨率的土壤湿度数据,为土壤湿度估测等方面提供理论依据和技术支持,实现水涝和干旱的实时监测,解决其生态环境问题。For typical soil microwave radiation characteristics, the traditional measurement method was analy- ed. Microwave radiation interference directly by measuring principle is studied. Soil moisture microwave radiation image reconstruction system based on compression perception is designed. Using the model to obtain credible, theo- retical basis and technical support are gained, such as soil moisture data of high resolution and soil moisture estima- tion provide. So real-time monitoring of flooding and drought is realized, and then the problem of the ecological en- vironment is solved.
