Abstract
2D Fourier transform analysis was carried out on radar sea clutter data. It was found that the gravity wave dispersion relation and its harmonics were clearly visible in the ω-k images. The dispersion curve and its harmonics were found to be distorted and rotated from their expected positions due to the existence of ocean currents. Measurements are made from the dispersion curves of both advancing and receding waves, and a significant difference is observed between the two measurements
