摘要
在光电跟踪设备的电视或红外自动跟踪系统中,引入目标的速度信息是提高跟踪精度的一种有效方法.为了得到目标的速度信息,设计了电视或红外脱靶量滞后时间的辨识方法以及目标速度预测的卡尔曼滤波方法,通过对电视或红外脱靶量信息同辨识出的脱靶量滞后时刻的仪器位置信息进行拟合,预测出被跟踪目标的速度信息,从而构成复合控制.仿真和实验结果表明,通过上述方法能够得出较为准确的目标速度信息,所构成的复合控制系统有效地提高了系统的跟踪精度.
Abstract
Inputting the velocity of moving target to the automatic tracking system of TV or infrared is an effective method to improve the tracking accuracy in electro-optical theodolite. In order to obtain the velocity of moving target, the methods of identifying the delay time of TV or infrared off-target and Kalman filter are designed. Fitting the TV or IR off-target for the code position of electro-optical theodolite and forecasting the velocity of being tracked target can compose compound control system. The simulation and test results show that velocity of moving target can be forecasted by fitting the target-missing quantity for instrument position quantity using the methods and tracking precision can be improved in servo-control system.
