基于遥测跟踪信息的光电经纬仪实时引导算法
|
摘要
针对遥测设备引导光电经纬仪的应用需求,提出了利用2套设备共视目标时光电经纬仪跟踪信息对遥测设备跟踪数据进行实时修正的一种算法,同时实现了跟踪残差的实时估计和外推。在光电经纬仪丢失目标时,需要采用低跟踪精度设备引导天线接近目标,然后转入自跟踪模式。利用修正后的遥测设备跟踪外推数据引导光电经纬仪捕获目标,提高了遥测设备实时引导精度。经实测数据验证,遥测设备引导拟合误差小于0.8'。
According to the demand of guiding the photoelectric theodolite with telemetry equipment,this paper proposes an algorithm that corrects the telemetry equipment data in real-time by using the photoelectric theodolite tracking information when the two sets of measurement equipment are tracking the target at the same time.This algorithm realizes real-time estimation and extrapolation of tracking residuals.When the photoelectric theodolite loses the target,low precision measurement equipment is required to guide the antenna to approach the target,then the antenna goes into the auto track mode.The corrected telemetry equipment information is used to lead the photoelectric theodolite to capture the target,which improves the guidance precision of the telemetry equipment. It has been verified by experimental data that the fitting error of processed telemetry data is less than 0.8'.
