摘要
目标指示精度作为光电跟踪设备的核心指标之一,是设备设计、制造和调试阶段重点关注的内容。安装于舰船等运动载体上的光电跟踪载荷,常常会增加稳定平台以控制光电跟踪设备的光轴和图像稳定。以一种带稳定平台的光电跟踪设备为例,建立了基于运动学的目标指向误差模型,并基于该模型对各几何误差进行了详细的分配。通过分配结果可知想要获得要求的0.5 mrad的目标指向精度,稳定平台及设备自身的轴线的平行度误差和测角误差的统计值应在7~12″的量级,该误差范围要求设备必须使用高精度测角元件及良好的装配工艺,并且在设备安装到载体上时使用标定方式进行误差补偿才可能达到。该研究方法及结论可用于指导类似产品的分析、装调和标校等工作。
Target pointing accuracy,as one of the core indicators of photoelectric tracking equipment,is the focus of attention in the equipment design,manufacturing and testing stages.The photoelectric tracking equipment installed on ships and other moving carriers often adds a stable platform to control the optical axis and image stabilization.Taking a photoelectric tracking and pointing device with a stable platform as an example,a kinematics-based target pointing error model is established is this paper.And based on this model,the geometric errors are assigned in detail,which can be used to guide the analysis,assembly and calibration of similar products.
