远距离动目标实时测试系统设计

Real-time test system for long range moving targets

设计的动目标实时测试系统,主要用于检查武器系统在"零飞"工作方式下的系统联动精度,测试被测系统的跟踪瞄准误差。在对远距离、动目标的监测中,采用双光路设计,长焦距、短焦双筒结构,电切换方式等实现对远、近目标的实时观测,双光筒安装在同一机体上,通过偏心镜框、偏心圈等保证两者的同轴度要求,夹具具有俯仰、方位的微调机构,方便在校炮时光轴与炮轴线一致性调节,并可实现数据的高精度、高保真测量。对焦距为50 mm和300 mm的镜筒静态测角精度进行了测试。实测结果表明:系统测角精度分别小于0.4 mrad和0.2 mrad,完全满足指标要求。该测试系统采用模块化设计,满足可靠性与通用性要求,可广泛应用于军事和民用等诸多领域。

A real-time test system for moving targets was designed to test the system coordination accuracy of weapon system operating at ＂0-fly＂ mode,and measure the tracking and pointing error.In the surveillance of long range moving targets,the system adopted double optical paths,a binocular tube of long focus and short focus,and an electric switching device to carry out the real-time observation for long and short range targets.The binocular tube was installed at the same machine body to ensure the concentricity by means of eccentric frame and eccentric ring.The fixture had fine tuning mechanism of pitch and azimuth to regulate the boresight between optical axis and gun axis.The measurement data with high precision and high fidelity were obtained.The static angle measurement accuracy of the tubes with 50 mm and 300 mm focal length was tested,and the experimental results showed that the accuracy was less than 0.4 mrad and 0.2 mrad respectively,which met the target requirements.This modular test system is reliable and can be widely used in military and civil applications.
