single-beam sonar

Single-beam sonar is a technology that uses a single, directed sound wave to map the underwater environment. It emits a sonar pulse straight down into the water and measures the time it takes for the echo to bounce back from the seafloor or objects. This information helps create a profile of the underwater terrain or detect objects. It's a straightforward method primarily used for quick, effective depth measurements and basic seabed mapping. While it provides a narrow, focused view, it is less detailed than multi-beam systems but is often suitable for smaller or less complex surveying tasks.
