一种车载数字式陀螺寻北仪的研究

Sudy of a Digital Cyro Northfinder for the Radar Vehicles

－本文介绍一种适合车载雷达等使用的数字式寻北陀螺仪。它立足于国内的现有条件，以计算罗经原理为基础，采用双位置力反馈平衡法和补角修正技术用以消除陀螺常值漂移的影响和在全方位上提高方位角的计算精度。

This paper proposes a digital gyro northfinder which is suitable forthe radar veh icles etc. It is based on the domestic present condition and the principle ofthe computing compass method.In order to eliminate the influence of the constant gyrodrift and to raise the azimuth computing accuracy in all azimuth,the force feedback balance and the supplemental angle Compensation techigue are used.
