In the past decade it became customary to relate the probability of appearance of extremely steep (the so-called freak, or rogue waves) to the value of the Benjamin-Feir Index (BFI) that represents the ratio of wave nonlinear-ity to the spectral width. This ratio appears naturally in the cubic Schrödinger equation that describes evolution of uni-directional(More)
—The problem of obtaining quantitative data on spatial ocean wave spectra from the images of the ocean surface by either regular SAR or along-track interferometric SAR (INSAR) is studied. The dominant mechanism which allows imaging of ocean waves by SAR/INSAR is the so-called velocity bunch-ing. This mechanism is essentially nonlinear. The theoretical(More)
