基于ZeroMQ消息通讯的多源空中目标跟踪处理平台设计

Design of Multi-Source Tracking Platform for Air Target Based on ZeroMQ Communication Library

摘要:

通过分析空中目标的信源异构性,提出使用ZeroMQ消息通讯库设计完成多源目标跟踪平台的设计方法,平台采用消息库的3种通信模式的组合与Json消息格式与各监测节点数据交互,为提高数据传输与交互能力,建立多线程Push-Poll数据推拉传输模式,且支持多源监测点实时接入与退出；本文采用欧式距离的最小二乘法二次曲线拟合方法进行航迹关联操作,有效的保证同一目标的航迹关联融合,可将目标属性融合、目标身份信息传递给目标综合识别,为后续的空中态势评估和威胁评估提供较为可靠的数据基础和保障。

Abstract:

By analyzing the source heterogeneity of air targets, a design method of multi-source target tracking platform using ZeroMQ message communication library is proposed. The platform works by the combination of the three communication modes and Json message format for data interaction with each monitoring node, and establishes multi-threaded Push-Poll transmission mode to support multi-source real-time monitoring points enter and exit in order to greatly improve the ability of data interaction processing. In this paper, the least-squares quadratic curve fitting method based on Euclidean distance is proposed to carry out the trajectory association operation. It is an effective way to ensure that the trajectory fusion information is related to the same air target and the target identity information is passed to the target comprehensive identification, which provides a more reliable data foundation and guarantee for the subsequent air situation assessment and threat assessment.
