一种可行的临近空间高超声速目标航迹起始方法

摘要

针对传统算法在临近空间高超声速目标航迹起始中存在的问题,提出了一种可行的多规则快速航迹起始方法.在分析临近空间高超声速目标特性的基础上,首先通过高度约束和速度约束减少杂波干扰,建立可能航迹,然后利用速度约束和加速度约束建立候选航迹,最后通过角度约束来剔除V字形航迹和确定真实航迹,并进行了Monte Carlo仿真.结果表明:该方法能够在杂波环境下对临近空间高超声速目标进行航迹起始,并且正确航迹起始概率高,虚假航迹起始概率低,平均航迹起始时间短,具有较好的工程应用前景.%Aimed at the existing problems in the traditional track initiation algorithm applied in the near space hypersonic target track initiation, a feasible multi-rules fast track initiation method is proposed. On the basis of analyzing the motion characteristic of near space hypersonic target, first the noise interference is reduced by the height constraint and speed constraint and the possible track is set up. Then, by using the velocity constraints and acceleration constraints the candidate track is established, and finally through the angle constraint V track is eliminated and the true path is determined. The Monte Carlo simulation results show that the use of the method can initiate near space hypersonic target tracks in the clutter environment, and has a high correct track initiation probability, low false track initiation probability and short average track initiation time. The method has a good prospect in engineering application.
