通过研究伺服系统对跟踪设备的影响,分析了跟踪设备在振颤状态下工作所受的干扰。以测试结果绘图,识别出跟踪线的俯仰角速度和方位角速度,能分辨出稳定的目标信号以及周期性的干扰信号。消除振颤干扰的方法,就是剔除受干扰的目标线的角速度值,以稳定的目标角速度替代,以测距结果配合无干扰的俯仰角与方位角,解算无干扰的弹道跟踪结果。

Through studying effect of servo system on tracking equipment, the paper analyzed interference of tracking equipment which is vibrating. The test results were used to plot graphics, the rate of pitch and azimuth velocity of tracking line could be identified, the stable target signal and periodic interference signals could be distinguished. The method of eliminating interference is to replace the interference angular velocity of the target line by a credible angular velocity, and adopt coordination of distance data with no interference pitching and azimuth angle to get better trajectory tracking results.
