Echo (single beam)

IMPULSE is a powerful tool for extracting information about the seabed from echosounder data. Seabed echoes, which can be read from a number of different formats, are processed to define boundaries of discrete acoustic classes of bottom type. Accuracy and repeatability are ensured by using only the first echo-return from the seabed. Seabed echoes are processed to present geo-referenced acoustic classes with no prior knowledge of seabed type using unsupervised classification techniques and automated 3-D clustering. Supervised classification based on a user-defined catalogue of seabed types is also available.

This approach provides unique flexibility in describing the seabed and correlating the data with other information to quantify seabed features or habitat.
