摘要
With the advantages of all-weather operation and certain penetration microwave remote sensing has become a very important technique,Its image is a function not only of the technical parameters of the sensor but also of the geometric forms and electrical properties,such as the dielectric constants and conductivity,of the ob jects on the ground.Minerals and rocks are the most widspread objects on the earth surface,hence their dielectric properties are of fundamental significance in microwave remote sensing.
