【摘要】：针对雷达探测临近空间高超声速目标受到雷达散射截面(RCS)随照射姿态异常分布、目标高速高机动飞行和大气环境等的影响,容易出现断续点迹,导致航迹起始困难的问题,提出了一种基于并行流水线的可变波门航迹起始方法.通过分析传统航迹起始方法存在的问题,结合临近空间高超声速目标的机动特性,设计了针对性更强的相关波门,采用流水线思想,并行执行针对不同周期出现断续点迹的航迹起始进程,实现多目标断续点迹的航迹起始.蒙特卡罗仿真结果表明:新方法正确航迹起始概率高,虚假航迹起始概率低,计算量小,具有一定工程实践性和可推广性.
[Abstract]:In view of the abnormal distribution of radar scattering cross section (RCSs) in the near space hypersonic target detected by radar, the high speed and high maneuvering flight of the target and the atmospheric environment, it is easy to appear intermittent track, which leads to the difficulty of track initiation. In this paper, a method of variable gate track initiation based on parallel pipeline is proposed. By analyzing the problems existing in traditional track initiation methods and combining with the maneuvering characteristics of hypersonic targets in adjacent space, a more targeted correlated-wave gate is designed. By using pipeline's thought, the track initiation process of discontinuous point tracks in different periods is carried out in parallel, and the track initiation of multi-target intermittent points is realized. The Monte Carlo simulation results show that the new method has a high probability of track initiation, and the results of Monte Carlo simulation show that the new method has a high probability of track initiation. The false track initiation probability is low, the calculation is small, and it has certain engineering practicability and extensibility.
