Abstract

See full text

Disclosed is an active sonar system capable of estimating a direction and a range of a target by using a sound pulse. A target range error can be estimated by the active sonar system, by applying a principle that a sound pulse used to detect an underwater target with consideration of a vertical structure of a sound velocity in water is reflected and refracted through a multipath not a linear path.
