Relationships of cause and effect which are the cornerstone of the phenomenon of observability of area of hydrophysical indignations from an underwater moving object, including its exit to a sea surface when lighting the area in the thickness of water by a laser beam and radiation of the sea surface over an object with a radar station signal are described in the article. In the stationary marine environment the laser beam creates a backscattering signal of a fixed level. In the area of hydrodynamic indignations from an underwater moving object the signal of a backscattering of variable brightness to the relevant structure and level of indignations is seen. The similar phenomenon of a backscattering of the electromagnetic radiation of radar station that creates glare effects on the screen of radar station in a zone of an exit of hydrodynamic indignations is observed on a water surface. It is shown that these phenomenons have similar nature caused by the change of dimensional orientation of dipoles of molecules and liquid crystals clusters of water in the field of the hydrodynamic indignations accompanying the moving of an underwater object. Establishing of this characteristic, in case of its confirmation by test data, meets the requirements of qualification of opening.
