Research progress of soil moisture monitoring based on microwave remote sensing

Soil moisture is an important influencing factors in agricultural production. Trying to get the soil moisture information and make artificial intervention and adjustment measures is important guarantee for keeping stable production. So, it is very important to monitor soil moisture content real-timly and efficiently. There are many methods for inversion soil moisture by remote sensing data, but microwave remote sensing is considered to be the best way nowadays. Main model, method, scope of application and advantages and disadvantages of passive and active microwave remote sensing for soil moisture were summarized. Optimal parameters selection of remote sensing monitoring soil moisture using radar was analyzed. The application prospect of the remote sensing monitoring soil moisture using microwave was done to provide reference for research of the remote sensing monitoring soil moisture using microwave.
