- Wavelet 2-D CWT FFT Radar image Wave spectrum Scaling
It is a useful way to gain ocean wave information using X-band nautical radar images. In this paper, an algorithm of 2-D CWT in spatial domain and 1-D FFT in time domain is presented for extracting the wave information. Firstly, the basic theory of 2-D continuous wavelet transform for space domain and its application for wave field analysis is introduced. Then, a scheme of analysis of the radar image sequence with this algorithm is given. By implementing this algorithm, the ocean wave spectrum and mean wave direction are extracted from the X-band radar images and compared with the in-situ data.
