| 摘 要： | 针对光纤陀螺输出噪声大、随机漂移难抑制，从而影响机载光电系统低频性能的问题，分析了系统中光纤陀螺输出的实测数据，根据其噪声特性建立了光纤陀螺噪声的AR2 模型。研究了基于卡尔曼滤波的光纤陀螺在机载光电系统中的应用方法。对比传统应用的滑动平均滤波，给出实验结果。结果表明:卡尔曼滤波能有效消除陀螺高频噪声，抑制系统的随机漂移，在一定程度上能够提高系统的低频工作性能。研究结果对机载系统中光纤陀螺的应用有较好的参考价值。

| Abstract: | Due to the high output noise and the random drift of fiber optic gyroscope (FOG) which bring on low dynamic performance of airborne electro-optical (E-O) system, the mea-sured data of FOG output in system was analyzed. According to the noise feature, the AR2 model of FOG was established. And a method of the Kalman filter based FOG in airborne E-O system was studied. Compared with the traditional moving average filter, the results of experiment were displayed. The results show that the high frequency noise can be filtered, and the random drift is restrained. Also the dynamic performance of system is improved effectively. These results provide reference values for the applications of FOG in airborne E-O system. |
