Investigation of Transmit and Receive Characteristics of Laboratory Model for the Parametric Echosounder

Investigation and operation of devices based on nonlinear interaction of high-intensity waves have been carried out for several decades. However, it is still a new tool to study the properties of the water environment and especially the upper layers of the seabed. This paper describes the results of tests of the new device that is intended to be applied for sounding underwater areas. The device has been designed and built in collaboration with the Department of Ultrasound of the Institute of Fundamental Scientific Researches of the Polish Academy of Sciences in Warsaw.
