基于分弧段角度法的雷达网重叠覆盖区域研究

合理规划雷达网的重叠覆盖区域以提升其整体能量利用率,是雷达网布站的核心要素之一。为了有效获取雷达网系统中重叠覆盖区域的具体特性,提出一种基于分弧段角度法的雷达网重叠覆盖区域计算方法,在各雷达的边界交点信息基础上,将各雷达的边界分割为一条条弧段,根据这些弧段采用分弧段角度法的搜索算法实现对雷达网重叠覆盖区域特性的计算。仿真结果表明,上述方法在多部雷达组成的雷达网区域范围内,可快速获取重叠覆盖区域的重叠层数、覆盖面积、覆盖雷达编号等信息,并分析获得各雷达及雷达网的重叠率,为雷达网布站提供有效的理论依据。

Study on the Characteristics of Overlapping Coverage Area in Radar Network Based on Sub-Arc Angle Method

It is one of the core elements of the radar network to plan the overlapping-coverage-area in the radar network to improve the overall energy utilization rate.In order to effectively obtain the specific characteristics of the overlapping-coverage-area in the radar network,this paper presents an approach based on of the sub-arc angle method.The boundaries of the radars were divided into line segments using the boundary intersection information of radars.According to these segments,the traversal search algorithm of the sub-arc angle method was used to calculate the overlapping-coverage-area.The simulation results show that the proposed method can quickly obtain the information of the overlapping layers,the coverage area,the coverage radar number of the overlapping-coverage-area in the radar network and overlap rate,and provide the effective theoretical basis for the deployment of radar network.
