This handbook contains basic theoretical information concerning analytical determination tasks and creation of spatial characteristics of most widespread types of acoustic antennas i.e. interferential and focused. Fundamentals of acoustic antennas classification are suggested. Formation of directional characteristics and determination of concentration coefficient for antennas of basic geometric shapes are considered in detail. The handbook contains information about some basic ways and techniques for the synthesis of above mentioned antenna types. Handbook materials have applied focus and are suitable for undergraduate and postgraduate students as well as engineering and scientific staff engaged into relevant issues in the field of acoustics.
