数字信号处理技术在新型惯导系统中应用的研究

数字信号处理是一种具有特殊结构的微处理器，可以用来快速实现各种数据信号处理算法，在新型惯导系统———光纤陀螺的应用中取得了很好的效果，使得陀螺系统质量轻，耗电少，成本低，寿命长，体积小，在军民品中都有广泛的应用前景。飞机、飞船和轮船一直都使用陀螺定位仪来导航，最新技术的定位仪是光纤陀螺，采用光纤技术的光纤陀螺很好地解决了汽车、建筑、工业机器人，天线系统和大型农场的农业机械定位问题，方便且灵敏的光纤陀螺在陀螺定位领域具有广泛的应用前景。基于萨格奈克效应（ＳａｇｎａｃＥｆｅｃｔ）的第一代干涉型光纤陀螺经过了２０年的研究历程，期间几乎所有内在与外在的噪声因素都得到了分析与消除，检测的方法也得到了很大的改进，使得光纤陀螺在军民两方面都有着重要的应用背景。

Research on the application of digital signal process in fiber optical gyroscope

Fiber optical gyroscope as an import dynamic sensor is widely used in military and civilian fields. Digital signal process is a high speed digital signal process chip. With it, fiber optical gyroscope can be made very small, light, long life, low cost and high precision etc. Aircraft, spacecraft and ships have been using gyroscopes to help them navigate, and recent advances in optical gyroscopes have bought this technology into the mainstream. These improved gyroscopes based on fiber optic technology are solving navigational problems in automobiles, construction and industrial vehicles, antenna systems and agriculture. Fiber optical gyroscopes, which are more accurate and easier to use, have prompted widespread advances in traditional gyroscope applications and developments in entirely new field. The first generation fiber optical gyroscope (I FOG), which is based on Sagnac Effect, has been studied for 20 years, during the time all of the noise factors have been almost clarified and eliminated. \ \ \ \
