Design of magnetic compass applied to aerial sonobuoy

本文简要分析磁通门传感器工作原理及其数学模型,根据航空声呐浮标实际应用需求,设计了一种基于磁通门传感器,具有功耗低、尺寸小、重量轻、可靠性高、误差小,具备工程实现批生产的磁罗盘。该磁罗盘经工程实践检验,工作稳定可靠,测方位均方根误差小于1°,为声呐浮标探测性能提供了有力保证。

This paper briefly analyzes the working principle and mathematical model of fluxgate sensor,and designs a magnetic compass based on fluxgate sensor,which has low power consumption,small size,light weight,high reliability and small error,and can achieve batch production by engineering,according to the actual application requirements of aviation sonobuoy.The magnetic compass works stably and reliably through engineering practice,and the root mean square error of azimuth measurement is less than 1 degree,which provides a strong guarantee for the detection performance of sononbuoy.
