Consistency in the simulation of microwave remote sensing of the ocean surface in conjunction with a new hydrodynamic theory

Under the two-scale hydrodynamic model for ocean surface waves, short waves are modulated hydrodynamically by long waves. An exact numerical simulation of the two-scale hydrodynamic process shows that the most commonly used modulation transfer function (MTF) is a linear approximation that does not capture all the features caused by the inherent nonlinear nature of the physical processes involved. This lack of information in the linear MTF begs the question: is there a need for a higher-order more consistent theory?
