Along with noise, reverberation - the backscattered part of the total reflection - forms the background to the detection of targets by an active sonar. In many environments, reverberation can be the dominant component of this background. It is therefore very important for the design of active sonars to have a good measure of its magnitude and how it varies with roughness and grazing angle.
