| Along with our country economy development, the aviation traffic transportation is busy day by day. Implements the omni-directional radar control at the airport has become the important topic which the radar ATC system (Air Traffic Control system) urgently awaits to be solved in our country. As an essential sub-system of the ATC system, "the multi-channel radar signal interface system" plays an important role in connecting the external radar signal to the ATC system. Using "embedded system" construction mode to realize protocol transformation for the multi-protocols radar signal is the key technology to the realization of "the multi-channel radar signal interface system".This paper introduces relevant concepts of the multi-protocols radar signal access,discusses the radar signal format and transmission protocol, the method of accessing the radar signal to the ATC system and the correlativity with TCP/IP protocol, and gives a detailed analysis from the angle of the product design process, physical structure, hardware and software realization and so on ,by using "embedded system" technology to realize protocol transformation for the multi-protocols radar signal. This product already took the radar ATC system a part is playing the vital role in the commercial aviation air traffic control work. |
