基于HY-2高度计波形数据的高分辨率有效波高反演算法研究
Research on inversion algorithm of significant wave height with high resolution based on waveform data from HY-2 altimeter
摘要
Abstract
Significant wave height (SWH) is one of the important parameters which describe the sea state. The SWH derived from altimeter has been widely applied in marine research. Based on waveform data from HY-2 altimeter,we developed an inversion algorithm of SWH with high resolution. The root mean square error (RMSE) condition was used to improve the ac-curacy of 20 Hz SWH. By applying this method in the waveform data of one pass,the result showed that the inversion algorithm is effective. Compared with the SWH derived from 1 s waveform,the spatial and temporal resolution of the SWH derived by this method could be in-creased by about 15 times and the accuracy is about 0.44 m. The SWH derived from HY-2 alti-meter 20 Hz waveform is reliable and could be applied for high resolution marine research.关键词
