Based on the analysis and research of the electromagnetic environment compatibility of airport and air station, a system for evaluating the electromagnetic environment compatibility of airport and air station is designed according to the civil aviation operation specifications and requirements. It focuses on the overlapping coverage between the navigation station and the navigation station, the influence of the ground environment on the distribution of electromagnetic signals, the shielding effect of typical obstacles on electromagnetic signals, and the interference of main interference sources on the electromagnetic environment The contents of the evaluation are as follows: to establish the radiation interference evaluation model; to visualize the electromagnetic signal distribution and interference sources of the air station, so as to effectively evaluate the electromagnetic environment around the civil aviation airport and the air station, and to provide an intuitive reference for the design of the electromagnetic protection zone.
