【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.更多还原

【Abstract】 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 w ere solved for the currently commercial underw ay w ater Hyperspectral Surface Acquisition Systems(SAS).The proposed method w as then examined using the in situ data.The results show ed that the underw ay-measured w ater-leaving radiance by SAS w ere quite consistent w ith these measured data at fixed stations.Meanw hile,the variation trends of the underw ay-measured w ater- leaving radiance by SAS w ere similar as the underw ay w ater turbidities.These results indicate that the proposed method for the data processing is credible.更多还原
