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

two-dimensional or three-dimensional space, the present invention is measured by underwater mobile phase flow field of precision navigation device and a method for relating as, by irradiating the light emitted from the light source in the water, such as a laser springing by the underwater movable body is the exact location of the moving object by measuring the water and wake analysis on two-dimensional or three-dimensional space of the flow field, direction of movement, the combination of information, such as size, etc. relates to non-contact underwater mobile navigation device and a method of obtaining precise. Water moving object navigation apparatus of the present invention is a light source for generating a laser beam, a scanner for sending a laser beam generated by the light source accurately in the desired measurement target region, and the light source from the region irradiated by the measuring light reflected laser beam detector the imaging optical system to be incident to, the reflected laser beam is provided to detect a known location, for detecting the frequency of the reflected laser beam, at least one or more detection from the optical detector and the optical detector comprising a light detecting unit reflected in the calculation of fluid velocity measurement by the Doppler effect from the region to a laser beam of the laser frequency and the frequency generated by the light source, and wherein the fluid comprises a flow field analysis for calculating the velocity of the moving object information from the water. ;
