摘要
The invention relates to a method for calculating a confidence echo signal V(t) that is exempt from multipath propagation effects, in particular a confidence underwater echo signal, said method comprising the following steps: - determining a time dependent measurement echo signal M(t), which has a superimposition of the confidence echo signal V(t) and a multipath echo signal S(t), such that in particular the measurement echo signal has an interference, - calculating an envelope curve U(t) of the measurement echo signal M(t), - calculating a period T of the envelope curve U(t) and using the measurement echo signal during an initial time period, which comprises a time span a*T, wherein a is a confidence factor less than or equal to 1 and T is the calculated period, such that the confidence echo signal V(t) that is exempt from multipath propagation effects is given for [t=0 to a*T].
