Research and Development of General Coverage Analysis Model for Air Traffic Control Stations

This paper studied the problem of signal coverage analysis of communication navigation and surveillance ground stations, analyzes the influence factors affecting radio signal transmission, including maximum range of the signal transmission, Line-of-Sight propagation model, terrain shelter, earth curvature, etc. A new methodology of general station coverage analysis is proposed, which reduces complex 3D spatial computation to 2D profile analysis. Key technologies are presented with the methodology, including elevation data extraction, spatial index construction, operating range model construction, terrain modification, coverage area extraction. Lastly, a station coverage impact evaluation system is developed authorship based WebGIS and the model. A field test is carried out by this system, and the results show that the proposed model has considerable practicability and generality and brings new thoughts to the development of signal coverage.
