Soviet Atmospherics Acoustics Research

Abstract : The development of low observable air vehicles by the United States coupled with the historic propensity of the Soviet Union toward the defense of its borders raises the possibility of Soviet development of acoustic systems for detection and tracking of air vehicles as part of such defenses. This report reviews and assesses Soviet research in atmospheric acoustics. Topics considered relevant were aircraft noise, background acoustic noise, propagation, meteorological remote sensing, microphone technology, processing of acoustic signals, and acoustic-gravity waves and ionospheric detection. This study should provide an indication of the maturity of the Soviet technology base required for the development of potential acoustic detection and tracking systems.
