Acousto-optic spectrum analyzers (AOSA) are very convenient devices in order to provide the radio air panoramic observation. They can represent the pattern of radio air situation in the way which is the most suitable for direct observation. The parallel data processing which is inherent to AOSA allows to increase the processing rate significantly in comparison with other kinds of panoramic radio receivers. The possibility to use different kinds of AOSA (including analyzers with space, time and composed space/time integration) have been considered, and the information processing rates of each kind have been analyzed from the point of view of the system optical information characteristics providing. The reasons of these parameters increasing limitation have been studied. On a level with calculations, the results of experimental implementation of AOSA-based panoramic receiver have been presented. We have used the space integration AOSA based on Bragg cell designed with tellurium dioxide single crystal with simultaneous analysis of 10MHz sub-band. The results of using of such panoramic receiver in the real system of radio air control have also been discussed.
