摘　　要：本文对一种以全功率微波辐射计为基础的新型微波辐射计———数字增益自动补偿微波辐射计进行了仿真研究。建立了微波辐射计系统各环节的数学模型并以此进行了仿真试验。仿真结果不仅证明了所建立的数学模型准确有效，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。In this paper the simulative study of a new type of microwave radiometer that is based on the total-power microwave radiometer——digital auto gain compensative microwave radiometer has been done. The mathematical models of all sections in the microwave radiometer system are built and on the basis of that the simulative test has been done. It is proved by simulative results that the mathematical models are accurate and effective. The simulative study results in this paper give an important reference for optimizing system design. Also they lay a foundation for the advancement of realizing system and environment debugging about spaceborne.
