舰载红外警戒系统多目标跟踪算法研究

A Multitarget Tracking Algorithm of Shipborne Infrared Surveillance System

多目标跟踪有着十分广泛的应用，目前国内外多目标跟踪的研究重点都集中在雷达等主动传感器上，但是对于红外的多目标跟踪领域却研究较少。对于红外系统，目标跟踪的最大特点是观测量只有角度，没有距离，这就使得传统的跟踪滤波问题遇到困难。通过讨论舰载红外警戒系统的多目标跟踪算法，分析目标与传感器的特点，提出了一整套多目标跟踪的算法。仿真结果表明，此套算法能满足工程应用的要求。

Multitarget tracking has widely application and the research is mainly concentrated on active sensors ,such as radar,but less on infrared ones.This paper discusses the algorithm of multitarget tracking for shipborne surveillance system.As we know,the measurements of shipborne infrared surveillance system are only two angles,which make the tracking problem become more difficult.This paper presents an algorithm to deal with the infrared tracking by analysing the characteristics of the target and the sensor.The simulation results show that the algorithm can satisfy the needs of the practical applications.
