Abstract
Disclosed herein are an apparatus and method for extracting ocean wave information. The apparatus for extracting ocean wave information includes a radar image reception unit for receiving a radar image from a radar antenna, a digital conversion unit for converting the received radar image into a digital format, an analysis preparation unit for setting analysis sections of the radar image and performing temporal accumulation on the analysis sections, a three-dimensional (3D) spectrum-conversion unit for converting accumulated analysis sections into a 3D spectrum in a 3D frequency domain by performing a temporal/spatial 3D Fast Fourier Transform (FFT) on the accumulated analysis sections, and an ocean wave information extraction unit for extracting ocean wave information based on the 3D spectrum.
