摘　　要：微波光子辅助的瞬时频率测量(IFM系统具有高时间带宽积、低功率损耗、轻系统质量以及抗电磁干扰等巨大优势。对目前国内外研究的IFM系统按照频率-空间、频率-时间和频率-幅度三种映射方式进行分类介绍,主要归纳比较了具有频率-幅度映射关系的IFM系统,针对其中存在的测量范围和测量精度之间的互换(Tradeoff问题,进一步引申到研究高精度可调谐测量范围的IFM技术,并对目前相关领域的研究进行了追踪报道。Microwave photonic-assisted instantaneous frequency measurement （IFM） system has many advan-tages such as high time-bandwidth product, low power consumption, light weight and anti-electromagnetic interfer-ence. Domestic and foreign IFM systems are introduced respectively according to three kinds of mapping modes such as frequency-space, frequency-time and frequency-amplitude. And IFM system with frequency-amplitude map-ping relationship is mainly concluded and compared. According to the trade-off problem between measurement range and accuracy, IFM researching technology with high accuracy and tunable measurement range is further pre-sented. And the current researches in the fields are reported.
