基于DEM的米波雷达阵地选择方法研究

Research on selection of meter-wave radar site based on DEM

米波雷达的最大效能发挥与其良好的阵地反射面紧密相关.针对雷达阵地的选择耗时、耗力问题,基于数字高程模型(DEM),对雷达天线架高、反射面的平坦度以及遮蔽角等影响米波雷达阵地选择的重要因素进行了定量分析,提出了一种米波雷达阵地选择的辅助决策方法.仿真结果表明,这种方法可实现米波雷达阵地的快速选择.

The exertion of maximum effectiveness of meter-wave radar is closely related to the better reflection surface of radar sites. In view of the issue of the selection of radar sites requiring much time and effort, this paper analyses quantitatively a few important factors of affecting the selection of meter-wave radar sites based on digital elevation model （DEM）, such as antenna frame height and the reflection surface flatness as well as the defiladed angle, and proposes an auxiliary decision-making method for selection of meter-wave radar sites. Simulation and test results illustrates that this proposed method can be available for fast selection of meter-wave radar sites.
