METHOD FOR ELIMINATING A REFERENCE UNDERWATER SOUND SIGNAL, SONAR DEVICE, AND WATERCRAFT

摘要

The invention relates to a method for eliminating a reference underwater sound signal from a resolved underwater sound signal, said method comprising the following steps: - detecting the resolved underwater sound signal by means of a sonar antenna, in particular a towed array sonar antenna, such that individual beams are obtained, which each contain a portion of the resolved underwater sound signal, and - adaptive filtering of the resolved underwater sound signal depending on the reference underwater sound signal.
