| Abstract: | The ground receiver of the microwave radiation scale-field is one of the main equipment for the outscaling of satellite radar.As the whole radar-system requires the very high precision, it is very important for its parameters of real time adjusting for the ground receiver of the system outscaling. A kind of the scheme of self-adjusting for the receiving channel of the ground receiver is designed, the adjusting principle and the adjusting process are setted forth, the design frame is given and the key technology is analysed in this paper. |
