基于折线分解的多雷达探测包络图绘制方法

A Polygon-Based Method of Computing Envelope of Multi-Radar Coverage

首先以雷达天线位置为中心,将单雷达探测包络线的弧线部分按等方位角分解为一定数量的折线段;然后,计算分解后多个雷达探测包络线之间的交点;最后,通过提取外围顶点得到多雷达联合探测包络线。仿真表明,对比传统计算方法,文中所提方法得到的多雷达探测范围和边界更加精确。

First ,the envelope of single radar coverage is divided by polygons according to equal azimuth angle. Second, the cross points of the divided polygons are computed. Last, the entire en- velope of multi-radar coverage is drafted through the marked points of border. Simulation results show that the envelope computed by the proposed method is more accurate than that by traditional methods.
