Abstract: 介绍了运用并矢Green函数和起伏逸散定理来计算平面分层媒质的辐射亮温,同时利用最小二乘法对多通道辐射计的模拟测量结果进行处理得到分层媒质厚度的方法.将该方法应用于月壤厚度的反演研究,在假定月壤如平面分层结构模型的情况下,得到了其厚度的反演结果,并对反演误差原因进行分析.
English Abstract: The final purpo se of th is paper is to est imate the th ickness of lunar so il.How ever, the th ickness can't be got tendirect ly, so we utilize m icrow ave radiometer to measu re the lunar su rface and make use of themeasu red values to obtain the app rox imate thickness.In the paper, first ly, w e in t roduce themeasu ring princip le of microwave radiometer that is u sed to measure the radiant energy of medium.For the diff icu lty in ob tain ing the radiat ion of inhomogeneou s medium that is ex istentun iversally in natu re,we divide the medium in to severalth in layers, and con sider each layer homogeneou s.Therefore,a method to calcu late the b righ tness temperatu re of layered medium based on Dyadic Green's Function and Fluctuat ion- D issipat ion theo rem is recommended in the paper. At the same t ime,we adopt the least- square method to p rocess the simu lated data by mu lt if requency microw ave radiometer.On the assumption of layered st ructu re for the lunarsoil,apply th ismethod to ret rieve the thickness of the lunar so ilw ith different measu ring error. Mo reover, a discu ssion on the inverse error is given.
