摘要： 光电对抗系统在机动状态下搜索和跟踪目标时，必须用位置陀螺代替码盘来确定目标方位角。但是，由于搜索轴陀螺存在漂移和累积误差，导致跟踪转台按照引导信息调转到位后目标无法进入跟踪视场，而且陀螺的漂移和累积误差是随时间和温度非线性变化的，很难直接进行修正。为了解决这个问题，提出了一种对引导信息进行间接动态校准的方法。

Abstract:

Azimuth of flying object must be produced by position gyroscope instead of encoder when electro-optical countermeasure system is searching and tracing objects on a moving truck. Because of temperature drift and cumulative error of gyroscope fixed on searching axis, flying object cannot be discovered by optical equipment for tracing. The temperature drift and cumulative error of position gyroscope are very hard to be corrected, because they are nonlinear with time and temperature. An indirect method to correct the guiding information is presented to solve the problem.

Key words: Mobile searching, Target tracking, Gyroscope drift, Compensation, Dynamic calibration
