一种快速自动寻北装置的研究

介绍了一种适合车载雷达、电子对抗等机动武器使用的快速自动寻北装置。它立足于国内现有技术和应用特点，以动调陀螺仪为测量元件，利用正切法双轴测速定北。为了消除陀螺仪漂移误差的影响，方案上采用了双位置多测量法和补角修正技术，以提高寻北装置全方位角的估算精度。整个测量过程由单片微机控制和计算，以快速自动准确测出真北方位角

STUDY ON A FAST AUTO COMPASS

This paper introduces a fast auto compass that is suitable for mobile weapons such as vehicle-borne radar and countermeasure devices. The compass, basing oneself upon current techniques and applied properties at home, can measure speed and point to north by tangent methods and with gyroscope as a dynamic tuning measuring unit. The two-position multimeasuring method and supplementary angle correcting method are used to eliminate the effect of drift error of gyroscope and increase the estimated precision of omnibearing angle of the compass. The whole measuring process is controlled and calculated by chip microcomputers to measure a ture north azimuth quickly, automatically and precisely.
