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.
Aiming at the problem that radar near-space hypersonic target is affected by the anomalous distribution of RCS, target high-speed and high-maneuver flight, atmospheric environment and so on, A method of starting a variable-width gate based on parallel pipeline is proposed.By analyzing the problems existing in the traditional method of starting a track and combining the maneuvering characteristics of the hypersonic target in the adjacent space, a more targeted correlation gate is designed, The idea of pipelining is used to execute the track initiation process in which the intermittent point traces occur in different periods in parallel, so as to realize the start of the track with multi-objective discontinuous point traces. Monte Carlo simulation results show that the new method has a high initial probability of track initiation , The initial probability of false track is low, the calculation is small, and it has a certain engineering practicability and extendability.
