利用变分结合正则化方法,对高度计风速资料在无辐散和有辐散两种情形下的背景风场进行调整,同时进行了数值试验.试验表明:高度计风速对背景风场的调整有积极作用,特别是高度计沿轨区域风场调整效果更为明显.对高度计后向散射截面进行了敏感性试验,当后向散射截面存在随机扰动时,利用高度计风速调整海面风场具有较强的抗噪性.最后进行实例试验,结果表明该方法是切实可行的.

To adjust non-divergent and divergent background wind fields by altimeter wind data, a novel approach, the variational regularization method, is presented. Numerical simulation results show that it is positive to use altimeter wind speed to adjust the background wind field, particularly effective in the altimeter track region. At the same time, the radar backscattering cross-section sensitivity is evaluated, when the backscattering cross-section contains noise, and the result proves that the above method can be used to suppress the noise. Finally, a real case shows that the above method is feasible and effective. This approach is an effective and reliable method of using the altimeter wind data to adjust the sea surface wind.-
