Technical Report on Hydroacoustics

The "Technical Report on Hydroacoustics" outlines how sound waves are used underwater to detect and study objects like fish, submarines, or seabed features. Hydroacoustics involves sending sound pulses into the water; when these sounds hit objects, echoes return that reveal their location, size, and shape. This technology aids in fisheries management, marine research, and naval security by providing accurate, non-intrusive ways to observe underwater environments. The report details methods, equipment, data interpretation, and best practices to ensure reliable and effective underwater acoustic measurements.
