多航迹交叉的时空判断方法研究

Research on Time-Space Judgement Method of Multi-Route Intersection

针对多巡航导弹协同作战中存在航迹交叉碰撞的问题,提出了多航迹交叉的时空判断模型。鉴于利用解析方法进行交叉判断比较复杂的特性,引入了航迹交叉判断的仿真判断方法-像素仿真法,并采用了像素点大小的多分辨率确定方法以提高交叉判断的即时性与准确性;考虑到巡航导弹在飞行过程中存在的偏差,引入了利用参数的区间估计值代替点估计值作为航迹交叉判断的基础值,从而提高了判断的可靠性。通过大量仿真计算表明,该判断模型描述准确、容易实现,可为多巡航导弹协同作战的航迹局部重规划提供相应的辅助信息。

In view of the problem that many cruise missiles may crash each other during their cooperative engagement,a Time-Space Judgement model of multi-route intersection was put forward.Owing to the complexity to judge based on analytic method,a pixel-simulation method was adopted,whose pixel size was dynamically gained by multi-resolution method in order to improve the judging speed and accuracy.Considering the deviation in the process of fly,the range estimation was used instead of dot estimation to get basic value of intersection judgement,which improved the judging credibility.Simulation results showed that this judgement model has the characteristics of exact description and easy realization,so it can provide assistant information for multi-cruise＇s route programming during their cooperative engagement.
