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.
