摘要
文章阐述了被动微波遥感和主动微波遥感的物理基础，着重介绍了亮温和散射系数与天线接收到的微波功率之间的线性关系，以及亮温和散射系数在测量土壤湿度和监测农作物生长情况方面的应用．
This paper reviews the physical foundation of the microwave remote sensing. The li- near relationships among the brightness temperature, scattering coefficient and the received microwave power by antenna are described. The brightness temperature and scattering coe- fficient can be used to measure the soil moisture and inspect crop growth in agriculture.
