Design and Realization of Visibility Algorithm in Radar Simulation

Based on the analysis of the familiar algorithms,a method to promote the computing performance of the visibility algorithm was put forward according to SRTM3 dataset.Firstly,by means of offline computing and online search,the minimum elevation array was achieved by arranging multiple SRTM3 datasets in accordance with the current radar station addresses.Then the visibility of the target was judged by comparing the target elevation with the value of the minimum elevation array of the corresponding mesh of grid.Finally,the visibility algorithm based on SRTMS dataset was accomplished in the radar simulator of the weapon cooperative datalink,and the demands for real-time generation of data satisfied.
