Method for determining an of more paths propagation effects have been removed, the sound of confidence - signal and for determining a distance and / or a direction to a sound source as well as a device and the vehicle

摘要

The present invention relates to a method for determining an of more paths propagation effects have been removed, the sound of confidence - signal v (t), in particular under water sound confidence - signal, with the following steps:– Determining a time-dependent measuring sound signal m (t), which is a superposition of the confidence sound - signal v (t) and a more paths sound - signal s (t), so that, in particular, the measuring sound signal has an interference,– Determining an enveloping u (t) of the measuring signal m (t sound),– Determining a period duration t of the envelope u (t)andUse of the measuring sound signal during an initial period, which comprises a time interval a · t, where a is a safety factor of less than or equal to 1 and t is the period duration is determined, so that the of more paths propagation effects have been removed, and sound confidence - signal v (t) for [t = 0 to a · t] is given.
