摘　　要：在日益复杂的电磁频谱环境中,精准获取完备的频谱态势信息是做出准确频谱决策的重要前提。首先,介绍了频谱测绘并对比了其与频谱感知的主要区别。接着,综述了现有频谱态势生成方法的研究现状。然后,提出了异构性、大尺度缺失、动态性、环境复杂性等挑战下的多维频谱态势压缩测绘技术研究工作,有效弥补了传统频谱态势生成方法忽略频谱态势感知过程而导致的频谱测绘框架不完整性,该研究可进一步为提升频谱利用效率、增强频谱安全维护以及强化军事电磁对抗的决策提供更精准的指导。最后,对未来频谱压缩测绘的发展趋势进行了展望。In the increasingly complex electromagnetic spectrum environment,accurately obtaining comprehensive spectrum situation is a crucial prerequisite for making precise spectrum decisions.First,the spectrum mapping was introduced and compared with spectrum sensing.Then,an in-depth review of existing spectrum situation generation methods was conducted.Next,multidimensional spectrum situation compressed mapping in the face of challenges such as heterogeneity,large scale missing data,time variability and environmental complexity was proposed.It effectively compensated for the incompleteness of the spectrum mapping framework caused by ignoring the spectrum situation sensing process in traditional spectrum situation generation methods.This could further provide more accurate guidance for enhancing spectrum utilization efficiency,strengthening spectrum security maintenance,and intensifying electromagnetic warfare decision-making.Lastly,the future development trends of spectrum compressed mapping were discussed.
