A SYSTEM FOR DETECTING SUBMARINE

摘要

PURPOSE: A seabed exploration system is provided to easily inundate electronic exploration apparatus for hydrothermal deposit exploration. CONSTITUTION: An EM(Electromagnetic Method) electronic exploration unit(1) is attachable in an unmanned midget submarine(10). A controller(700) controls the EM electronic exploration unit. A mounting unit(30) loads the controller in the unmanned midget submarine. A motion sensor senses the motion of the unmanned midget submarine. The EM electronic exploration unit comprises a connecting frame, a transmission coil, and reception coil, and bucking coil. The connecting coil connects both end portions of an external frame. The transmission coil is installed in the external frame and forms a primary magnetic field. The reception coil is installed on the center of the external frame and detects magnetic field strength of a secondary magnetic field formed by the primary magnetic field. The bucking coil is installed on the outer circumference of the reception coil and eliminates a contributory portion of the primary magnetic field.
