Noise-protected antenna for a pulse acoustic atmospheric sounder

Antenna systems of modern acoustic atmospheric sounding technique (SODAR) are among the most functionally important and expensive of its constituents. The successful versatile SODAR application is directly related to the high-quality indexes of the acoustic antenna, such as noise protection in relation to acoustic ambient noise. In the present work, on an example of worked out by authors SODAR, the questions of acoustic noise protected hybrid budget antenna creation are considered in a practical way. Main attention is given to the original construction of transceiving acoustic phased array which is a constituent of the antenna.
