Abstract

History of the development of combined acousto-electromagnetic antennas for the atmosphere radioacoustic sounding equipment is briefly considered. Advantages and shortages of combined reflector antennas and combined PAAs are pointed out. The modulation effect of sounding electromagnetic radiation at the sound frequency, which is inherent in the combined antennas, is analyzed. Particular attention is given to the statistical aspects of acoustic PAA operation - to the influence of randomness in the sources distribution in antennas on their radiation patterns.
