An antenna system providing for transmission and reception of a sonic signal is one of the most important parts of a sodar (sonic radar). Reflector-type parabolic antennas are now widely used in Russia because of their relatively simple design. In this paper, we present the results of theoretical and experimental studies of a high-frequency acoustic antenna designed for sensing of the lower atmosphere up to about 200 m altitudes.
