Abstract

A functional flexible photonics-assisted frequency measurement (PFM) based on polarization multiplexing and coarse/accurate (C/A) compensation is proposed. Under the same system configuration, it can support fast frequency measuring with moderate accuracy (<0.2 GHz) and wideband range (1 GHz-31 GHz) for radar warning receiver (RWR) using a Mach-Zehnder interferometer (MZI). Moreover, based on the coarse measurement result, a more accurate frequency measurement can be given for electronic countermeasures receiver (ECMR). It is implemented by stimulated Brillouin scattering and improves the accuracy to 20 MHz. Especially, the electro-optic (E/O) modulation section is performed with the assistance of polarization multiplexing, which improves the stability and simplifies the system.
