The book "Spatial-temporal processing of hydroacoustic information" by B. G. Guseva is a deep and comprehensive study devoted to one of the most urgent and complex areas of science - hydroacoustics. This publication will be of particular interest to specialists in the field of acoustics, oceanography, as well as engineers and researchers working with underwater technologies and signal processing systems. Author, B. G. Gusev is known for his many years of research in the field of hydroacoustics and signal processing. His works are not only of high scientific value, but also of practical orientation, which makes them useful for a wide range of readers. In this book, Gusev shares his knowledge and experience, exploring methods and systems that allow the efficient processing of hydroacoustic information in a complex underwater environment. The book covers a wide range of topics, ranging from the basics of hydroacoustics to modern methods of data processing. It explores various aspects of space-time signal processing, allowing the reader to gain a deeper understanding of how acoustic waves interact with the environment and how these interactions can be used to produce useful information. Gusev not only explains the theoretical foundations, but also provides practical examples, which makes the material accessible and understandable even for those who are just beginning to get acquainted with this topic. Who is this book intended for? First of all, it will be of interest to students and graduate students studying acoustics, physics and related disciplines . It will also be useful for professionals working in the field of marine technology, ecology and environmental protection. Engineers involved in the development of underwater systems and equipment will find in it a lot of useful information that will help them in their work. The topics raised in the book are of great importance for modern society. Hydroacoustics plays a key role in the monitoring of marine ecosystems, the search for underwater objects and even in military technology. In the context of global climate change and growing interest in ocean exploration, understanding of the principles of hydroacoustic systems is becoming increasingly relevant. Gusev’s book helps readers understand the importance of these technologies and their impact on our future. The author’s style is distinguished by clarity and logical presentation . Gusev skillfully combines a scientific approach with practical examples, which allows the reader not only to assimilate information, but also to apply it in practice.
