Other AbstractIn order to research the signal preprocessing and the inversion method of the ocean wave, the simulation model of a space-borne real aperture radar spectrometer based on signal flow is established. The block diagrams for the modulation spectrum and directional spectrum simulation are provided. Using the simulation model, different ocean wave spectrum model and ocean conditons are simulated. The results show that the retrieved modulation spectrum and referenced modulation spectrum are highly related. What is more, a method used to correct the influence of the ocean anisotropy is proposed. The ocean anisotropy can be corrected by using the normalized modulation coefficient. The simulation results show that the directional spectrum retrieval error is significantly reduced after modulation coefficient correction, especially in the conditon that wind wave and swell wave exist simultaneously and are vertical to each other. The energy integral error of directional spectrum reduces to 2% from 20%.
