摘　　要：船载磁探测器测得的磁场信号中,除期望的船舶坐标系下的地磁场信号外,还包含多种干扰磁场信号,需采取抗干扰措施才能使其满足测磁要求。论文在分析各种干扰磁场信号特性及其排除方法,以及以往四个主航向上的水平抗干扰方法的基础上,对四个主航向上的三分量抗干扰技术进行了理论建模、算法实现以及工程适用性等研究,并通过Matlab仿真验证了该技术的可行性。Not only the geomagnetic signal in ship coordinate system which is expected,but also several kinds of interference magnetic signals which are not expected,it makes up the magnetic signal measured by the magnetic detector on the ship,in order to meet the requirements,anti-interference measures must be taken.In this paper,based on the characteristics and eliminating method of the interference magnetic signals,and the horizontal anti-interference method on four main headings in the past has been analysed,the theoretical modeling,algorithm implementation and engineering applicability of the three-component anti-interference technology on four main headings have been studied,and Matlab simulation has been took out to verify its feasibility.
