摘　　要：针对传统理论计算的雷达威力偏差大、检飞雷达威力实时更新难的问题,提出了一种基于多粒度网格划分(MGGD)的雷达威力在线评估方法.利用多粒度网格的空间分割思想,首先将雷达探测空域按照不同的粒度径向分割成网格块;然后将雷达情报中的威力样本数据映射到空间网格中;最后在网格中采用滑窗的方式过滤网格中的冗余数据,实时计算和更新网格中数据点和威力值.实验结果表明,该方法能够有效逼近雷达系统当前状态下的实际最大探测能力,为清晰掌握雷达情报保障能力提供了数据支撑.In order to address the problem of large deviation of radar coverage calculated by use of traditional theory and the difficulty in updating real-time data of radar coverage in testing radar’s performance of aircraft detection, this paper proposes an online evaluation method of radar coverage based on multi-granularity grid division(MGGD). Firstly, the spatial segmentation idea of multi-granularity grid is used to divide the radar detection airspace into grid blocks radially according to different granularity, and then the coverage sample data of radar intelligence is mapped to the spatial grid. Finally, the redundant data in the grid is filtered by sliding window in the grid, and the data points and radar coverage values in the grid are computed and updated in real time. Experiment results show that the proposed method can effectively approximate the actual maximum detection capability of the radar system under the current state, which provides data backing for clearly grasping the radar intelligence support capability.
