摘要
针对红外警戒系统只有角度测量的情况,将传感器获取的目标角度信息转化为扭转角序列,并以扭转角作为度量单位,采用修正的K最近邻域算法(MK-NN算法)实时地实现角度航迹的关联。仿真结果表明,中等密集环境下正确关联概率在第6帧时可达95%,其计算量明显低于传统的统计检验方法,能有效地提高系统的实时性,易于工程实现。
The angle-only measurements are obtained on tracking tragets by IRST. The angle data are converted to the hinge angle sequence. The argle track association is achieved on real time by using MK-NN algorithm. Simulation results show that the probability of correct association reaches 95% in the sixth sample frame under moderate dense targets and noise. The computational complexity is lower than the classical statistical test algorithm. The algorithm satisfies the needs of practical application.
