图象制导系统的陀螺稳象技术研究

Research of Gyro-stuabilization in Image Guidance System

图象制导系统导引头的目标成象传感器是由陀螺直接稳定的,陀螺转子运动不平衡引起的振动与“绕动”直接影响到图象的稳定及整弹性能。该文从理论上对此进行分析和讨论,由此得出振动、绕动调试的合理依据及方法,从而避免了调试过程中的盲目性。

The target imaging sensor of seeker in an image guidance system is directly stabilized by gyro, hence the image stabilization and guidance performance are affected by vibration and nutation cased by dynamical unbalance of gyro rotator. The effects of vibration and nutation are theoretically analysed so as to furnish the proper basis and way for eliminating the vibration and nutation and avoiding the blindness during tuning.
