摘要
A novel algorithm is developed to estimate the signal-to-noise ratio (SNR) for the significant wave height (SWH) inversion of the ocean wave fields imaged by X-band radar. The proposed algorithm utilizes the geometric relationship of the linear dispersion relation for gravity sea surface waves to separate signal and noise without the determination of sea surface current. Compared with the traditional SNR-based method, the SWH derived by using this proposed method matches well with that measured by an in situ buoy nearby.
