A method for eliminating - water of a reference sound signal, as well as sonar device and watercraft

摘要

The invention relates to a method for eliminating - water of a reference sound signal from a spatially resolved water sound signal, said method comprising the steps of:– Determination of the spatially resolved water sound signal by means of a sound under water - antenna, in particular a towed sonar antenna, so that individual beams are present, each of which has a part of the spatially resolved water sound signal and– adaptive filters of the spatially resolved water sound signal in a function of the reference sound signal - water.
