Microwave photonics polyharmonic systems for instantaneous frequency measuring of radiosignals

This article describes how to develop design principles of microwave photonics systems for microwave signals instantaneous frequency measuring based on the use of them for original Il’in-Morozov’s amplitude-phase modulation conversion of optical carrier, subsequent “frequency-amplitude” measurement conversion in the fiber Bragg grating with special reflective contour. The aim is to prove the possibility of measurement frequency range expanding, increasing of measurements resolution at the "low" frequencies range and sensitivity at the "high" frequencies one.
