摘　　要：提出了一种方便、通用的防空雷达网覆盖面积计算方法。该方法基于单雷达在指定高度层上的探测包络数据,借助Qt平台实现对各包络数据的图形计算处理,通过多边形面积计算及坐标转换投影实现覆盖面积计算。文中基于Qt平台实现了多图形的交、并集运算,给出了根据单雷达探测包络计算雷达网探测外包络的准确计算方法,提高了外包络计算准确性,并给出了覆盖面积、覆盖系数、盲区系数计算。最后,介绍了该算法在实际系统中的应用及计算分析,为防空效能评估系统提供了有力支撑。A simple and universal method of computing the air defense coverage area is proposed in this paper. Based on Qt, the method accomplishes data and figure calculations according to single radar envelope data, and finishes the coverage area calculation by polygonal area calculation and map projection transformation. The paper improves the accuracy of radar net＇s envelope data by Qt＇s figure intersection and union operation. The calculation process of coverage coefficient and blind area coefficient is also pro- vided. Finally, the calculation analysis and application in practical systems are introduced, providing strong support for the air de- fense effectiveness evaluation system.
