MODE OF ACOUSTICS SOUNDING OF MARINE MEDIUM IN CONDITIONS OF SHALLOW WATER Russian patent published in 2007 - IPC G01S15/00 G01S3/16 

FIELD: the invention refers to hydro acoustics and designed for investigation of underwater situation and definition of hydro physical non-uniformity of the marine medium in the conditions of shallow waters.

SUBSTANCE: the mode of acoustics sounding of marine medium in conditions of a shelf zone is in preliminary definition of density and speed of the sounding in a bottom layer of water and in the bottom, in emission of a complex signal, its reception in distant point by three identical on sensitiveness orthogonally oriented in space receivers of oscillating speed V_x,V_y,V_z having a common phase center and installed at a distance from the bottom, not prevailing the length of the wave in water on a working frequency of the signal. Then the de-escalation of the received and emitted signals is calculated, maximums of voltage in corresponding channels of the receiver of oscillating speed (Uv_x)I(Uv_y)I(Vv_y)i are defined for each I-fragment of the signal are defined, horizontal and vertical angles are defined in accordance to them on reduced mathematical correlations.

EFFECT: increases accuracy of definition of vertical angles(angles of sliding).
