Abstract :
Imaging of the ocean wave field with a nautical radar is strongly influenced by shadowing, creating nonlinearity. Therefore, besides the fundamental mode, harmonics of the imaged wave field are generated at the image spectrum. It is shown that it is possible to identify the different modes of the wavenumber-frequency spectrum. A spectrum of simulated radar images is compared with a wave energy spectrum, which has been taken during ERS-1 CAL/VAL
