摘要
针对密集杂波环境下航迹自动起始困难的问题, 根据杂波和目标的空间分布特征, 采用了网格连通的概念对观测空间进行网格划分并基于相应的准则形成连通域, 通过对连通域的分析实现对点迹的预处理, 然后对预处理之后的点迹进行航迹起始处理, 通过减少航迹起始判断的观测点数目来减少计算量, 实现快速的航迹起始, 并利用仿真试验和实际数据验证了该方法工程应用的可行性。
Abstract
To overcome the difficulty of all-range and all-azimuth automatic track initiation in the dense clutter environment, the concept of grid connection is adopted for grid partitioning of the observation space to form an independent connected area based on certain criteria, according to the spatial distribution characteristics of clutters and targets. The trace points are preprocessed based on the analysis of the connected area. After the pre-processing, the track-initiation processing is implemented by using the measurements of targets. The calculation cost is reduced by means of decreasing the number of observation points used for judging track initiation, and thus the automatic track initiation is implemented rapidly. The feasibility of the method in engineering applications has been verified by simulations and the actual data.
