Abstract:

Based on ocean wave data obtained from the flight experiments of airborne ocean wave spectrometer principle prototype, signal processing and ocean wave parameter inversion algorithm are studied. The ocean wave directional spectrum and some ocean wave relevant parameters are got by data processing using ocean wave spectrum inverse algorithm. Then, to study the propagation characteristics of ocean wave in this sea area, ocean wave propagation is stimulated through shallow ocean wave model Kadomtsev-Petviashivilli(KP) equation. The measurement results by the ocean wave spectrometer almost agree with the simulated result, show that the inverse algorithm is effective and the airborne ocean wave spectrometer can measure the ocean wave spectrum fairly precise, which lays a good foundation for development of space-borne ocean wave spectrometer.
