APPARATUS AND METHOD FOR SEARCHING A MOVING UNDERWATER TARGET USING SPATIAL MEASUREMENT OF WAKE FIELDS GENERATED BY THE MOVING TARGET AND AIR VEHICLE LOADED WITH THE SAME APPARATUS

摘要

PURPOSE: An underwater moving body precise exploration device, an exploration method and an aerial vehicle with the exploration device are provided to measure and analyze a flow field of water stream generated by an underwater moving body on a 2D or 3D space. CONSTITUTION: A scanner(2) irradiates a laser beam of a laser light source to a specific object area in underwater. An imaging optical system(3) transmits the laser beam to an optical detection unit(4). The laser beam is reflected after irradiating the laser beam from the laser light source to the specific object area. The optical detection unit(4) is installed in a location for sensing the reflected laser beam. The optical detection unit senses and processes the reflected laser beam by an optical method. A flow field analysis unit(5) analyzes flow field data of water stream generated by an underwater moving body on a 2D or 3D space by using the reflected laser beam and optical information of an irradiated laser beam.
