摘要
提出一种基于卡尔曼滤波的光电跟踪脱靶量滞后脱靶量补偿方法;在高精度光电跟踪设备中,光电跟踪器输出的脱靶量在时间上存在滞后,严重影响复合控制中的跟踪目标精度,使得跟踪存在较大滞后;为了在复合控制中能够得到更精确的目标速度信息,引入了kalman预测滤波技术,通过预测飞行物体的运动轨迹,进而提前进行方向预判,从而提高了跟踪精度;仿真试验表明,通过预测外推可以比较精确地预测目标运动速度,跟踪滞后性得到有效弥补。
Put forward a kind of based on kalman filter photoelectric tracking miss--distance lag miss--distance compensation method. In high precision photoelectric tracking equipment, photoelectric tracking device in the output of evaluating the lag time there, the serious influence compound control the tracking target accuracy, make tracking introduced, simulation. For in the compound control can give more accurate target speed information, introduce a kalman filtering technology forecast, through the forecast track flying object, and then to ad- vance direction sentence beforehand, so as to increase the tracking accuracy. The simulation results show that the prediction can push through more precise forecast target movement speed, tracking hysteresis effectively make up.
