摘　　要：矢量水听器获取质点的矢量信息时,要求该质点的坐标系保持恒定,而海洋环境复杂多变,矢量水听器的姿态容易发生变化,因此姿态修正成为矢量水听器应用过程中的一个重要问题,为此设计了一套电子罗盘系统。该系统体积小、测量精度高达0.1°,超低功耗,实验数据证明,利用罗盘进行姿态修正,可以大幅度提高矢量水听器方位估计稳定性。Vector hydrophone for direction finding particle velocity vector hydrophone pickup can be maintain- ed in a fixed coordinate system,and the marine environment is complex and changeable,the vector hydrophone attitude will change,so the attitude correction of vector hydrophone in the application process becomes an important problem,this paper has designed a set of electronic compass system.This system small volume,high measurement accuracy up to 0. 1 degrees,low Power consumption,experimental data show that the attitude corre- ction using a compass,can greatly improve the stability of estimation of vector hydrophone range.
