In this article, we present the results of research of photonic systems for spectrum analysis of the SHF-band radio signals based on "frequency-amplitude" transformation in contours of amplification or absorption of stimulated Mandelstam- Brillouin scattering (SMBS) approximation in single-mode optical fiber. Using of such systems as a means of spectrum analysis of the SHF-band radio signals allows us to eliminate many of the shortcomings of similar systems.
