Abstract
Radar net power range display fusing is a common requirement of electronic warfare simulation. Though GDI+ and other third-party tools could be used to solve the problems of region merging effectively, there are still some defects like uncontrollable calculation process and results. To solve these problems, in this paper we proposed one region merging algorithm based on the polygon boolean operation principle. Firstly, we introduce four key steps of the algorithm: adjusting clockwise order, computing intersection, extracting the envelope and region merging. Secondly, the data structure of the algorithm is presented. Finally, to verify the algorithm validity, we use some radar network scenarios as samples and analyze the algorithm performance briefly. The results show that when the radar number is less than 50 and the drawing interval is bigger than 15 °, this algorithm can meet the demand of radar net power range display fusing in semi-real time and real time simulation.
