A method and apparatus for continuous estimating parameters sonarer under water sound sources

摘要

A method for the continuous estimating parameters sonarer under water sound sources, characterized by the,a) that space sonarer transmitter is received and noises are recorded,b) from the space noises, at most for each technically a dissolvable direction, relative to the signal sink, the exact course of the transmitted signal is determined, and in the case ofc) n - beinflussten signals, the a - priori unknown sound sources parameters: the point in time of its radiation as well as the distance to the receiver, the speed and the course of the emittent,d) in the case of not doppler - influenced signals: the point in time of its radiation, with the aid of the requirement for as low as possible a time dependence of the reverberation in one direction and after a maximum independence to one, several or all other echo signals of the reverberation from other directions, to the secondary condition a physically consistent doppler - displacement is estimated.
