摘　　要：针对已有的雷达地形遮蔽盲区计算方法中地形建模不够准确,或者算法通用性不强等问题,提出基于地球曲率的雷达探测空间计算算法。首先,分析地形遮蔽下的雷达探测效果;然后,定义了雷达最低可见角。在此基础上,计算雷达在不同地点上空的俯仰探测角度范围,进而得到雷达在不同地点上空的高度探测范围。仿真结果表明该算法通用性强、易于实现,且时间复杂度低,具有较高的应用价值。In order to solve the problems of inaccuracy of terrain modeling or poor generality of algorithm in the existing calculation methods of radar terrain blind space,a radar detection space calculation algorithm based on earth curvature is proposed. Firstly,the radar detection effect under terrain masking is analyzed,and then the minimum detectable angle of radar if defined. On this base,the elevation detection angle range of radar over different locations is calculated,and then the height detection range of radar over different locations is obtained. Simulation results show that the algorithm is universal,easy to implement,low time complexity,and has high application value.
