摘　　要：面对频谱资源日益紧缺、频谱安全日益严峻以及频谱对抗日益激烈的挑战,电磁频谱态势研究急需从感知向认知跃升。本文从多层频谱态势认知体系模型与机理、跨域多维电磁特征提取与融合、频谱语义态势高效补全与预测、频谱行为精准推理与意图识别4个方面出发,综述了频谱态势认知理论与方法的研究现状。面对复杂多域多维电磁频谱环境与多样化任务的挑战,需要构建从“数据到语义”“语义到行为”“单域到跨域”“单层到多层”的频谱态势认知理论技术体系,该体系可为提升天地一体信息网络频谱利用效率、维护空中电波安全有序以及夺取电磁频谱制电磁权/电磁频谱战优势奠定频谱态势理论技术基础。With the increasing scarcity of spectrum resources,the increasing severity of radio regulations,and the increasing fierceness of electromagnetic warfare,the research of the electromagnetic spectrum situational has to transit from spectrum perception to spectrum cognition.This paper reviews the current research status of the theories and methods for spectrum situational cognition from four aspects:The mathematical models and fundamental mechanisms for a multi-layer spectrum situational cognition system,the extraction and fusion of cross-region multi-dimensional electromagnetic features,the efficient completion and prediction for spectrum situation,and the precise inference and intention judgment for spectrum-related behaviors.To address the complex multi-domain multi-dimensional electromagnetic spectrum environment and diversified tasks,it is critical to develop a framework of spectrum situational cognition from“data to semantics”“semantics to behaviors”“a single region to cross regions”“a single layer to multi layers”.This framework builds up foundations,both theoretically and technically,for efficient spectrum sharing in space-terrestrial integrated information networks,efficient radio regulations,and advantages in the electromagnetic spectrum warfare.
