摘　　要：军事雷达的不断发展使得武器装备面临严峻挑战,如何提高武器装备的隐身性能成为国内外学者的研究重点。能够将入射雷达波吸收并转化成热能的吸波材料被广泛应用于雷达隐身技术中。铁氧体、碳材料等传统吸波涂层材料技术成熟且已被大规模应用,但还无法实现吸波材料在实际应用中的“薄、轻、宽、强”等性能。超材料作为一类具有天然常规材料所不具备的超常物理特性的人工材料,为雷达吸波材料的设计带来无限可能。吸波超材料与传统吸波材料的融合有望实现恶劣战争环境对吸波材料的更高要求。从传统吸波材料、吸波超材料、传统吸波材料与吸波超材料的融合3个方面综述了吸波材料的研究现状,并展望了吸波材料的未来发展。The continuous development of military radar makes weapons and equipment face severe challeges.How to improve the stealth performance of weapons has become the research focus of scholars at home and abroad.Absorbing materials that can absorb and convert incident radar waves into heat energy are widely used in radar stealth technology.Traditional microwave absorbing coating materials,such as ferrite and carbon materials,have been widely used,but they cannot achieve the properties of“thin,light,wide and strong”in practical applications.Metamaterials,as a kind of artificial materials with extraordinary physical properties that conventional materials do not have,bring infinite possibilities for the design of radar absorbing materials.The fusion of metamaterial absorbers and traditional material absorbers is expected to achieve better absorber used in harsh war environments.In this paper,the research status of microwave absorbing materials is summarized for three aspects:traditional material absorbers,metamaterial absorbers,and the fusion of traditional material absorbers and metamaterial absorbers.Finally,the future development of microwave absorbing materials is prospected.
