摘要
为提高车载光电系统作战性能,对系统跟踪精度的影响因素与误差源进行分析。进而根据误差的产生条件,对其进行分类与合成,推导出系统误差与随机误差的计算公式。并以某一光电系统为例分析计算,最后提出跟踪精度提高与补偿的方法。结果表明,该光电系统的方位系统误差为0.325 mrad,俯仰系统误差为0.283 mrad,随机误差为0.276 mrad,均小于0.5 mrad,满足技术指标要求。
In order to improve the operational performance of vehicle-mounted electro-optical system, the influence factorsand error sources of the system tracking accuracy are analyzed. Then according to the producing conditions of theerror,the calculation formula of system error and random error are deduced. Taking a certain electro-optical system asan example, a method to improve the tracking accuracy and compensation was proposed through analysis and calculation.The results show that the azimuth system error,the elevation system error and the random error of the system are0. 325 mrad,0. 283 mrad and 0. 276 mrad respectively, and the results are all less than 0. 5 mrad,which meets the requirementof technical index.
