The most basic requirement is to provide continuous and reliable flight dynamic information for monitoring equipment within the range of air traffic control. ADS-B is the future major surveillance technology determined by the International Civil Aviation Organization. Based on the theory of electromagnetic wave and electromagnetic field, this paper analyzes the influence of space propagation on ADS-B signal coverage. Combined with DEM topography, the sightline range cut-off distance of ADS-B was calculated. The base station antenna is simulated and the antenna radiation performance is calculated. In this paper, the actual application of ADS-B base station signal coverage is simulated and the methods and measures to improve the signal coverage of base station is put forward. According to the experiment results, this method meets the needs of engineering application, has certain practical value, and provides a basis for the site selection of base stations.
