集成式随动装置目标引导信息动态校准方法研究

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。

Dynamic Calibration Method of Leading information in Integrated Following Equipment

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.
