运动红外单站跟踪空中目标的方向估计方法

红外探测器只能测量运动目标的方位角和俯仰角,难以获取目标的距离信息.运动红外探测器所测量的运动目标不完全信息,无法在直角坐标系下有效对三维运动目标进行滤波与跟踪.针对这一问题,提出了运动红外单站跟踪运动目标的参数航迹滤波方法:该方法利用传感器测量到的目标方位角和俯仰角信患,根据假设的目标运动模型,直接对目标航迹方向进行...

Method to estimate the trajectory of space target with infrared mono-station

Infrared detector can only obtain the azimuth angle and elevation angle of the target which is hard to get the information of distance.Especially for the incomplete information measured by motional infrared detector,it is impossible to track three dimensional objects in rectangular coordinates.Aiming at this issue,a new approach,the algorithm of filtering and smoothing with parameters based on motional infrared mono-station,is proposed to estimate the direction of flight path,with the utilization of the information of azimuth angle and elevation angle measured by the sensors,and then the problem of target tracking by motional infrared mono-station is well solved.As is shown in the simulation,the model has a good estimation of the course of the target as well as the direction from the missile to targets.The algorithm has high value of theory and application.
