摘要 本文基于HY-2高度计与Jason-2高度计时空匹配数据集,将匹配点Jason-2的海况偏差视为真值、HY-2的有效波高和风速为变量,利用最小二乘法建立海况偏差估计六参数模型。将所建模型应用于HY-2第70、71cycle数据,结果表明:改进后的海况偏差估计参数模型优于传统海况偏差估计参数模型,能够有效提高HY-2的海况偏差估计精度。 In this paper,its data sets base on HY-2 satellite altimeter data and Jason-2 satellite altimeter data within the scope of decided time and space.The sea state bias(SSB)of Jason-2 at the matching point is considered as the true value,the effective wave height(SWH)and wind speed(U)of HY-2 as variables.Using the least square method to establish the SSB parameter model,the model is applied to the 70 and 71cylce data in the HY-2 altimeter.The result shows that the improved SSB estimation parameter model is superior to the traditional SSB estimation parameter model,the improved SSB estimation parameter model can effectively improve the estimations accuracy of SSB in the HY-2 altimeter.
