一种新的单站红外目标纯方位参数航迹滤波方法

红外单站只能测量目标的角度信息,难以获取目标的距离信息,无法在直角坐标系下有效对3维目标进行跟踪.该文提出一种新的纯方位参数航迹滤波方法,该算法避免传统方法中需采用多站交叉定位的思路,根据红外传感器测量速率较高的特点,直接利用单传感器测量的方位角序列,对目标航迹参数进行估计,较好地解决了单站的目标跟踪问题.仿真结果表明,该方法对直线运动或机动目标具有良好的跟踪性能.

A New Parameterized Track Filtering Method for Single-station Based Bearing-only Infrared Target

Only the angle information of the targets can be obtained by infrared single-station. It is hard to get the distance information, which makes it impossible to track 3D objects in rectangular coordinates. A new algorithm is proposed for estimating the tracking parameters of bearings-only measurements, which avoids the complexity of traditional multi-station cross-location algorithms. According to the characteristics of high measurement rate by infrared sensors, azimuth sequences, obtained by an infrared single-station sensor, are utilized to measure the track parameters. Target tracking problems for single station could be solved effectively in such bearing-only mode. Simulation results show that the proposed algorithm has good filtering performance in tracking maneuvering targets, as well as the targets with straight-line motion.
