Nonlinear Evolution of Waves Based on Radar Wave Measurements and the mNLS Equation

Radar wave measurement is the only means of obtaining highly accurate wave information that can be carried by ship, reflecting the real-time and actual wave conditions of a ship's current navigation area. The nonlinear evolution of waves can simultaneously be effectively described by a model based on the mNLS equation. The purpose of this paper is to combine a radar wave measurement system with the mNLS equation by selecting the radar wave spectrum with application conditions of epsilon <= 0.3 and Delta f/f(0) <= 0.2 to construct initial conditions and simulate the nonlinear evolution of waves.
