Abstract:X-band dual polarization weather radar is to identify the particle morphology and particle size distribution,one of the important equipment of information. The basic principle,composition and technical characteristics of radar are introduced from the perspective of system design. The system is designed to send and receive,reduce the loss of echo signal in the feeder system and avoid the influence of the indicator fluctuations of the rotating joint and other devices on the polarization parameters of the two lines.

Keywords:weather radar;system design;sending and receiving equipment front;loss
