摘　　要：磁通门罗盘是一种新型罗盘。此罗盘的关键部件是探头,探头主要是由高导磁的软磁材料做成的磁环和线圈组成。当在初级线圈加上交变的激励信号时,即可得到与次级线圈在地磁场中相对应的磁方位角。本文介绍其原理,并对其进行了理论分析。The flux-gate compass is a new type of compass.It does not have a- ny moving parts such as bearings, magnets and thus has overcome most of the problems encountered with the mechanical compass.The heart of the compass is a saturable magnetic toroid with high permeability driven by an alternating exciting signal.The output of the secondabry windings gives the azimuth proportional to the orientation of the windings in the earth's magnetic field. The principle of operation of the flux-gate compass and the calcula- tion of the second harmonic equation are introduced in this paper.
