[仿真]Microwave Transfer Models and Brightness temperature simulations of MWS for Remote

Abstract－China has launched a microwave radiometer SI, t:=D  
(MWS) to the Moon orbit to detect regolith information of the 8T?D#,/  
lunar surface. It is the first time that humankind directly *~0U4kw+  
applies sensed brightness temperature to investigate the lunar P^[y~I#{  
surface information by passive microwave sensor on lunar ODNZLCB~t  
orbit. Therefore, it is necessary to set up theoretical models to 9|NH5A"H.  
describe lunar surface microwave transfer process, as well as Q:U>nm>xA  
heat conduction. These models will finally used for retrieving Jp"yb`w  
lunar surface information on regolith depths. PWk\#dJN&  
In this paper, we will derive a microwave radiative Nk;ywC"e;  
transfer model for simulating MWS brightness temperature. }*?,&9/_)  
We solve numerically the integral equation of the lunar soil by 9Yd"Y-  
dividing the soil into many layers, and at each layer, emission, 1\ Gxk&  
multi-reflection, and attenuation to the sub-layer radiation are Wn-'iD+9<  
all summed into a formula. The contributions of the ,#U[

of brightness temperature due to soil depth variation.
