Аннотация
The paper discusses the conditions imposed on the spectrum of an emitted signal for which the interferometric method of detecting a moving sound source in shallow water is applicable for vector-scalar receivers. It is shown that a normalized spectrogram representing a two-dimensional Fourier transform of the interferometric pattern is identical for all four acoustic field components and combinations thereof. Results of a field experiment in which a vector-scalar receiver was applied are presented. The interference immunity of the method is considered for different field components in the case of isotropic interference.
