被动微波反演裸露区土壤水分综述

Review of the Bare Field Soil Moisture Retrieval from Passive Microwave

被动微波具有全天候、穿透性以及不受云的影响等特征,使其在反演土壤水分时具有很大的优势。通过研究发现,被动微波遥感是反演土壤水分的各种技术中最有效的方法之一。概括了主要的被动微波传感器并从被动微波遥感的原理出发,针对被动微波遥感裸露区地表随机粗糙面的模型以及土壤水分反演算法作了简要介绍。

Passive microwave have great advantage in retrieval soil moisture because of the characteristics of all-weather,penetrability and not affected by the cloud.Through study people found that passive microwave is one of the most effective methods in retrieval soil moisture in various technologies.This paper summarizes the major passive microwave sensors and the principle of passive remote sensing,and introduces the bare field randomly rough surface passive microwave model and soil moisture algorithm.
