Paper Abstract

The main features and measured performances of acousto-optic spectrum analyzer (AOS) modules for RATAN-600 spectrometer backend are considered, special attention having been paid to frequency and amplitude stability which is of great importance while faint radio sources observations. AOS based RATAN-600 spectrometric complex performance was tested during observations of mesospheric water vapor thermal radiation at 22.2 GHz. Preliminary results of spectral measurements obtainable with AOS module allowed the vertical profile of water vapor concentration for altitude region from 55 km to 80 km to be reconstructed.
