| Abstract: | 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. |
| Keywords: | instantaneous frequency measurement microwave photonic frequency-amplitude mapping |
