Abstract:
Abstract Due to the fact that sound waves are the most effective carrier for underwater information transmission, the detection of underwater acoustic signals has become a key link in optimizing the performance of transponders in underwater positioning systems. In this paper, the signal processing module of the hydroacoustic transponder is designed to address the problem of low detection accuracy of the transponder due to the propagation deformation of hydroacoustic signals in hydroacoustic channels. The module uses the TMS320C6748 processor to achieve the transmission, acquisition, and detect

Abstract The article discusses hydroacoustic receiving systems, consisting of combined receivers, and the processing of the received hydroacoustic signals. Each module of the sonar system has four channels for receiving information. Spectral processing was carried out using sixteen information parameters, which made it possible to achieve the maximum noise immunity of the receiving system. Correlation processing of signals confirmed the high correlation of signals on the elements of the receiving hydroacoustic system.

The key elements in the operation of modern underwater robotic systems are hydroacoustic communication and navigation systems. Hydroacoustic data transmission channels are designed in such a way that the transmitted information signals must be resistant to various types of interference and distortion, even without preliminary estimates of the channel parameters, due to their significant non-stationarity because of the roughness of the sea surface, currents, and the movement of underwater vehicles. Furthermore, due to the high mobility of underwater vehicles, the transmission time of navigation

It is therefore important to understand the origin, transport, and depositional processes of the various terrestrial sedimentary components in a depositional system.

Abstract:
Over the past decades, signal processing methods have become increasingly widespread due to the progress of computer technology and the achievement of significant results. Signal processing is understood as the process of restoring an information message that will be accessible to human perception. To achieve this goal, there are already many mathematical methods that are applied depending on the specific problem. Working with a large data sample creates the need to create signal processing systems. An equally important factor is the limited access for human experimentation in natural conditio
