Interference suppression method for group signals in sonar location device uses multiplication of group signal with weighting signal for eliminating reception signal phase errors

摘要

The interference suppression method has the group signal, obtained by addition of the reception signals provided by the electroacoustic transducers (31) of a reception antenna (30), multiplied with a weighting signal for suppression of interference by elimination of the reception signal phase errors. The weighting signal is calculated by providing a complex signal from each reception signal and summating the complex signals after normalization.
