Calculation of the Principal Characteristics of a Parametric Radiating Antenna

Presents the calculation of the main characteristics of the parametric radiating antenna for the given signals with pumping frequencies of 86 kHz for a tone signal, 87...97 kHz for a signal with linear frequency modulation (LFM) and a signal with a difference frequency of 1..11 kHz (LFM signal). The construction of the directivity characteristics at the pumping frequencies, at the difference and geometric mean frequency of the probing signals is performed. Recommendations are given for the selection of the type and materials of electroacoustic transducers, on the basis of which the parametric radiating antenna is built. The obtained results can be used in practice in the design and development of hydroacoustic means of vertical bottom probing with a parametric operating mode.
