主动微波土壤湿度反演进展研究

ctive microwave remote sensing monitoring soil moisture with the all-day, all-weather, high spatial resolution and penetration of the surface features have certain characteristics, has become the main way to monitor soil moisture. This paper briefly introduces the principle of active microwave remote sensing, summarizing and analyzing the main models, aimed at understanding the different characteristics of these models to the better accurate and choice the soil moisture model. Finally discusses the trend of future development of soil moisture and active microwave remote sensing technology.
