一种通用航迹起始模型

A Universal Track Initiation Model

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。

Based on a survey of current track initiation methods, this article focuses on research of track initia tion models under airborne pulse Doppler radar environment for engineering implementation, and one universal track initiation model suitable for various track initiation conditions is presented. The main idea is that one intermediate track is added to the current common track initiation model, and that the whole track initiation process is processed by stages, for which different track initiation methods and thresholds are used. This made the physical concept of the overall track initiation process and the processing steps much clearer, the threshold setting more reasonable, and file management more convenient. Furthermore, track initiation split and missing, which are problems common to the current track initiation model, are improved. Monte Carlo simulation results show that the universal track initiation model can improve design flexibility, standardize track initiation deign, and increase the probability of correct track initiation.
