摘　　要：针对商业化的走航水体高光谱观测系统SAS(Surface Acquisition Systems),提出了在走航观测的复杂条件下,针对关键角度的计算、水气界面反射系数的估算和异常数据剔除等问题,开发出实用的数据处理方法,并利用现场数据进行了检验.结果表明,SAS走航观测获得的离水辐亮度与站点测量结果具有很好的一致性,且与同步走航水体浊度的变化趋势一致,具有较好的可靠性.The problems about calculation of the key angle, estimation of the reflection coefficient at the moisture interface, and elimination of abnormal data in situ measurement under complex conditions were solved for the currently com- mercial underway water Hyperspectral Surface Acquisition Systems （SAS）. The proposed method was then examined using the in situ data. The results showed that the underway-measured water-leaving radiance by SAS were quite consistent with these measured data at fixed stations. Meanwhile, the variation trends of the underway-measured water - leaving radiance by SAS were similar as the underway water turbidities. These results indicate that the proposed method for the data processing is credible.
