Study of improving the optoelectronic system capability to track moving targets by using acceleration delay compensation

在速度滞后补偿的基础上,提出了一种加速度滞后补偿提高光电跟踪系统跟踪快速运动目标精度的方法,并将其应用于提高电视跟踪稳态精度中。结合电视跟踪器补偿技术,在保证最大跟踪误差不大于3′的条件下,将目前光电经纬仪电视跟踪系统跟踪最大角速度30°/s和最大角加速度12°/s2能力,提高到跟踪最大角速度50°/s、最大角加速度30°/s2。仿真和实验结果表明,该方法简单实用,可以在速度滞后补偿提高跟踪精度的基础上,大大提高系统跟踪快速运动目标跟踪精度的能力。在实际工程应用中,所述方法取得显著效果。

The equivalent sine target method to measure the tracking precision of optoelectronic tracking system was presented. The concept of acceleration delay compensation was put forward. By using acceleration delay compensation, the tracking capability of optoelectronic tracking system was promoted to track fast moving targets at maximal 50°/s angular velocity and maximal 30°/s^2 angular acceleration other than maximal 30°/s angular velocity and maximal 12°/s^2 angular acceleration while the maximal tracking error was still less than 3′. The simulation and experiment results show that the theoretical analysis is correct and it is very valuable for engineering.
