FIELD: fishery underwater acoustics.
SUBSTANCE: vessel being involved in finding poaching fishing tool tows underwater apparatus by means of cable-rope. There is satellite navigation system on the vessel which allows high-precision determining coordinates of vessel. There is also computer on the vessel providing control for operation of all sections disposed on vessel and in towed underwater apparatus. Computer finally solves the problems of efficient finding, detecting, identifying and determining of space coordinates of poaching fishing tools located on ground or bottom deposit layer. Sea biological objects generate wide-band signals which objects sit in traps connected to each other by halyard.
EFFECT: improved efficiency of finding.
