The results of theoretical and experimental studies are discussed aiming at the justification of potential vector-phase methods for various hydroacoustics applications. These studies have greatly contributed to the active introduction of the vector-phase methods for sonar measurements. The advantages of vector-phase methods, especially in underwater acoustics are most manifested at significant limitation of the spatial region for their propagation in the medium. A qualitative shift exists in the case of a single combined receiving module (CRM), which provides a new “characteristic” of the point receiving system, viz., detectability of the acoustic source. Another CRM feature is the applicability of a fundamentally new (as concerns hydrophone systems) processing algorithm based on direct measurement of acoustic flux (energy), i.e., the release of its part that is dependent on field anisotropy or point sources in the environment.
