摘　　要：文章介绍了星载微波散射计多耦合回路内定标方法的原理及接收机的几种接收通道形式;在此基础上,从隔离度、定标精度等方面进行分析,提出了一种多耦合回路内定标的星载散射计接收通道设计方案。In this paper,the principle of the multi-path internal calibration of spaceborne microwave scatterometer and several forms of receiver channel are introduced. On the basis of above discussion, some issues concerning the system isolation degree, the precision of calibration are addressed. Furthermore, a design scheme of receive channel is presented.
