The Analysis And Simulation Of The Location Of ADS-B Ground Station Based On The Mixed Algorithm Of GA And PSO

With the rapid development of civil aviation recent years, traditional surveillance technology can not meet the increasing demand of the aviation transportation. The new surveillance technology Automatic Dependent Surveillance-Broadcast is widely used in our country gradually. In order to achieve the optimal safety index and maximize the use of resources, the location of the ADS-B ground station has become the key problems.Researching on mixed algorithm for ADS-B ground station location analysis, the following work is mainly carried out: Firstly, ADS-B technology is briefly introduced. Then in order to provide the basis for the location of ADS-B ground station, relevant location factor is analyzed and civil aviation standards are summarized. Secondly, genetic algorithm and particle swarm optimization algorithm are analyzed and simulated. The advantage of mixed algorithm is verified through simple location test function. Thirdly, ADS-B ground station antenna characteristics are analyzed. The real terrain, the effect of cone of silence and the curvature of the earth are taken into account. Then the electromagnetic coverage model of ADS-B ground station is simulated and verified through the visualization of real terrain. The connection between the coverage area and the matrix is established and rate of coverage is quantized. After the true map data is loaded, ADS-B ground station location is simulated by mixed algorithm. Finally, proper ADS-B ground station location scheme is given out, the coverage and redundancy are analyzed for different flight levels. Additionally, these results are visualized in the MATLAB(2D) and U-GIS(3D). The GUI interface is edited to achieve the simulation and the display of ADS-B ground station location at any flight level.
