摘要
This invention describes a method and system for classifying a survey area according to an attribute of the seabed. More particularly, the classification technique uses echoes recorded from sonar pings transmitted towards the seabed. The echoes are resampled at a sampling frequency which takes into account the depth of the water, sediment conditions generally in the area and the duration of the ping, resulting in an improved classification of the seabed according to the selected attribute.
