<p><P>PROBLEM TO BE SOLVED: To provide a water surface profile measuring device that uses an observation device comparatively easy to be installed and managed and measures the water surface profile of sea or the like, and to provide a water surface profile method. <P>SOLUTION: The water surface profile measuring device includes a plurality of radars 10 that radiate pulse-like microwaves to the water surface, receive back scattered waves plural times at each of predetermined timings, detect the back scattered waves at each of a plurality of measuring points, and output a plurality of Doppler signals corresponding to the respective back scattered waves. The plurality of Doppler signals output by the respective radars 10 are used to generate information concerning the movement of water particles on the water surface at the plurality of measuring point provided in the radiation directions of the pulse-like microwaves of the radars, and the advancing direction of waves is determined based on the information indicating angles formed by the radiation directions of the pulse-like microwaves of the respective radars 10 and the advancing direction of waves. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
