This paper focused on the key technology of the ground verification experiment of airborne windshear weather radar system. Completed the ground veriifcation experiment of airborne windshear weather radar system. In the microwave darkroom, the simulated windshear echo data were used to generate microwave signals. And these signals were sent to weather radar. Besides the border condition and parameters which can cause windshear warning are studied and veriifed. Based on the theory of weather radar, simulated the windshear echo signal, designed the avionic platform for weather radar and verify the key technology of the ground verification experiment of airborne windshear weather radar system. The result of ground system experiments indicates the method for simulation of windshear wind ifeld signal and ground simulation veriifcation system is valid. It provides technology support for developing the airborne windshear weather radar.
