Аннотация

New technologies for the digital recording of broadband complex signals have made it possible to develop and create laboratory autonomous multichannel equipment to record bioacoustic activity on a digital medium with low power consumption and the possibility of continuous recording for up to 4 h. The equipment operates under the control of a fit-PC computer with the Windows operating system and the PowerGraph program for digital recording in a frequency band of the analog path of up to 600 kHz. Equipment testing recorded paradoxical signals from toothed whales with a frequency band exceeding 200 kHz. Signals with an extended frequency band were recorded in a laboratory experiment in open water while solving the problem of target tracking and in an experiment with provocation of acoustic communication behavior.
