摘要
针对制导弹药的毁伤目标的运动特性,目标的运动方向特征提取比较复杂,难以直接获得直观的方向的问题,提出一种基于时空方向能量理论的目标运动特征提取方法,在设计方向能量滤波器组成时将集群目标的运动方向分成三个方向,而单目标的机动性能要高于集群目标,因此设计时将单目标的时空方向能力滤波器组精确地分为八方向。最后,仿真实验证明,时空方向能量特征可以对集群目标和单目标进行运动方向约束。
For the motion characteristics of precision-guided munitions,the direction of motion characteristics ofthe target extraction is more complex,and it is difficult to directly obtain the intuitive direction of the problem.Focusing on this problem,a new analysis method is proposed by the spatial-temporal orientation energy. In thedesign direction of energy filter will be the direction of movement of the target cluster is divided into three directions,and the performance of single motor the target is higher than that of group targets,so the design of space-time direction single objective ability filter accurately divided into eight directions. Experimental results show thatthe proposed method has good stability to restrict the motion of the cluster target and the single target.
