Embodiment Construction

[0060] The present invention provides a functionally flexible photonics-assisted frequency measurement method and device, which will be further described below with reference to the accompanying drawings.

[0061] 1. Functionally flexible photonics-assisted frequency measurement device

[0062] system link such as figure 1 shown, a functional flexible photonics-assisted frequency measurement device based on the combination of stimulated Brillouin scattering and Mach-Zehnder interference, including a laser source, an electrical amplifier, a dual-polarization Mach-Zehnder modulator DPol-DMZM, and an erbium-doped fiber. Amplifier EDFA, polarization controller PC, coarse / fine frequency measurement module, processing module. The optical carrier generated by the laser is input into a dual-polarization Mach-Zehnder modulator, and is subjected to carrier-suppressed double-sideband modulation and phase modulation by an unknown RF signal and a scanning signal, respectively, to obtain a...

Description

technical field [0001] The invention relates to the field of microwave photon frequency measurement, in particular to a functional flexible photonics-assisted frequency measurement method and device based on the combination of stimulated Brillouin scattering and Mach-Zehnder interference. Background technique [0002] In modern radar early warning and electronic countermeasure systems, frequency measurement is an important task to identify intercepted microwave signals, which is usually done by specially designed receivers. Ideally, a wide frequency measurement range, high accuracy and fast response speed are expected. However, it is difficult to satisfy these requirements simultaneously based on the existing technology. Therefore, a compromise based on different applications would be better. Typically, the Radar Warning Receiver RWR is used to provide real-time warning, which focuses more on a wide frequency range to cover all threats and fast measurement response, but ac...
