Abstract
In this paper, SSR surveillance network covering problem with obstructing affected by surface features and lakes was studied. The purpose is to improve the performance of SSR surveillance network, thus ensure the efficiency and safety management in airspace. The objective is to minimize the number of radar and the decision variable is the site of radar. Firstly, radar network covering problem without obstructing affect is studied. An approximation UFC algorithm was provided. Secondly, covering problem with shelter influence was taken into account. Additional notations were given and SFC algorithm was excuted for this problem. Finally, SSR surveillance network covering problem with obstructing affected by mountains and lakes was studied. We conclude the performance of our algorithm combined with an easy heuristic is stable and can always save one or two radar in the whole system compared to the easy heuristic algorithm. Keywords-SSR Surveillance Network: optimization; coverage problem; approximation algorithm; heuristic
