摘　　要：为提高导航、制导与引信等系统的目标探测和抗干扰能力,摆脱对GPS、伽利略等系统的依赖,在阐述非晶丝材料特性及其巨磁阻抗效应概念内涵和分析该领域国内外研究状况基础上,提出了一种基于非晶丝巨磁阻抗效应的微磁物理场探测新体制。讨论了导航、制导及引信等系统要实现基于非晶丝的微磁物理场探测需解决的几个关键技术,分别就非晶丝磁探测基本技术理论、非晶丝磁滞特性及其抑制/补偿技术、非晶丝磁探测器的高灵敏度实现技术、目标探测与识别、非晶丝探测器弹(轨)道环境适应性等问题进行了分析和阐述,并给出了其基本技术途径。最后对该体制的应用前景进行了展望。The purpose of this study was to improve the detecting sensitivity and anti-interference of navigation and guidance systems; and make them independent of GPS and Galileo Positioning System. Based on the concepts of the amorphous wire properties and Giant Magneto-lmpedance （GMI） effect and the present research status at home and abroad, a kind of new micro-magnetic-field detecting system, which is based on amorphous wire＇s GMI effect, was proposed. A few of key techniques on micro-magnetic detection in navigation and guidance systems were discussed, and relational technical measures were analyzed, including fundamental theory about amorphous wire micro-magnetic detector, amorphous wire magnetic hysteresis characteristic and suppression/ compensation techniques, high-sensitivity detecting methods, target detection ＆ recognition, suitability in trajectory/orbit, etc. Finally, the application development of the detecting system was prospected.
