摘要
为保证某型号双波段机载光电平台的可见光电视、红外跟踪测量系统在跟踪精度室内检测过程中能够同时接收目标并可以任意切换,提出了一种可产生双目标的新型检测装置。文中主要分析了机载平台与检测装置之间的空间位置关系和数学模型,描述了检测装置的两个目标在做圆周运动的同时进行同步调整的必要性,并建立了同步调整误差模型。实验表明,当检测装置的两个目标以周期为20 s做匀速圆周运动时,旋转轴均方根误差为1.21″,两轴系同步误差为19.2″,满足机载平台跟踪精度的检测要求。
A new system is developed for testing the tracking error of dual-band airborne optoelectronic platform with visual TV/IR tracking and measurement systems.Visual TV/IR tracking and measurement systems detect the targets at the same time and they can be switched arbitrarily with this new testing device.The paper analyzes the space relationship and mathematical model between airborne platform and testing device.The necessity of double targets′ angle synchronous adjustment is given.At last,the mathematical model of synchronous error is built.The experiment results indicate that the RMS error of swivel bearing is 1.21″,and the RMS error of adjustment bearing is 19.2″,when the double targets of testing device move circularly with the period of 20 s.The results show that the resting device meets the demands of testing the tracking error of airborne platform.
