在研究现有航迹起始方法的基础上,在机载脉冲多普勒雷达环境下,从工程实现背景出发重点研究航迹起始模型,提出了一种适应于各类航迹起始的通用航迹起始模型。其主要思想是在归纳现有普通航迹起始模型的基础上,在模型中增加了一级中间航迹,并对整个航迹起始过程进行了分阶段处理,在不同的处理阶段采用不同的航迹起始方法和门限。使得整个航迹起始过程物理概念更明确,层次更清晰,门限设置更合理,文件管理更方便,改善了现有普通航迹起始模型存在的航迹起始分裂和丢失问题。蒙特卡罗模拟结果表明:通用模型增加了设计的灵活性,规范了航迹起始设计方法,提高了航迹起始正确概率。
On the basis of studying the initial method of track initiation, under the background of airborne pulsed Doppler radar, the initial model of track initiation is studied from the background of engineering realization, and a new adaptive model for track initiation is proposed. Common track starting model. The main idea of this paper is to add an intermediate track to the model based on the initial model of the common track, and to process the whole process of starting the track in different stages, Trajectory starting method and threshold. Which makes the physical concept of starting process of the whole track clearer and clearer, the threshold setting is more reasonable, and the document management is more convenient, which improves the splitting and loss of track initiation existing in the existing common track starting model. The Monte Carlo simulation results show that the universal model increases the flexibility of design, standardizes the initial design of track, and improves the correct probability of track initiation.
