数字增益自动补偿微波辐射计是一种新型的微波辐射计，它能很好地实现增益补偿，有效地提高微波辐射计性能，更适合星载使用．本文对以全功率微波辐射计为基础的数字增益自动补偿微波辐射计进行仿真．分析了全功率微波辐射计的特点，并在此基础上，提出了在频程跨度很大时实现系统频域仿真的有效方法．仿真结果不仅证明所采用的方法是有效的，而且为优化系统设计提供了重要参考，同时也为进一步实现星载环境仿真调试奠定了基础

Abstract

Digital auto gain compensative microwave radiometer is a new type of microwave radiometer.It can compensate gain very well and raises efficiently the properties of microwave radiometer.So it is more suited to spaceborne microwae remote sensing.In this paper

simulation of the digital auto gain compensative microwave radiometer based on the total power microwave radiometer has been done.The specificity of the total power microwave radiometer is analyzed.On the basis of that

a method of realizing system frequency region simulation is suggested when the span of frequency range is very large.It is proved by simulative results that this method is effective

and it gives an important reference to optimizing system design.Also it lays a foundation for the advancement of realizing spaceborne environment debugging.
