Abstract :
Interference pattern of acoustic field can be used to estimate target parameters. Target parameters, such as depth, distance and velocity, etc. can be estimated by extracting the period of interference frequency for interference spectrum or the parameters of interference curve. It indicates that there exists the farthest interference distance when there is only sea surface reflection.
