摘要

Method and apparatus for the echo localization of different objects, of layers, banks or multiple layers, whose acoustic impulses coming from an emitter pulse are not sufficiently indicated in the register, characterized in that the acoustic impulses not sufficiently recorded are indicated more clearly in such that the entire acoustic signal covering the respective acoustic pulses is first demodulated, being then influenced by one or several blocks with time-dependent values of the frequencies in such a way that the sectors of the demodulated acoustic signal, which carry frequencies of greater order, they are preferred over other sectors coming from reflective surfaces that are also in the acoustic triangle and result in the demodulated acoustic signal frequencies of lower order and finally the more or less corrected voltage course of the acoustic signal is used for the detachment of the indication of pes on the sea floor or below the surface of the sea, as well as heterogeneity of objects in the echo sounding installation.
