| 摘 要： | 基于充分挖掘卫星遥感应用于海洋监测能力的需求,通过海上试验测量船舶含气泡尾迹海水的物理、光学特征,研究气泡群对不同水体光学特征的影响,例如离水辐亮度、遥感反射率.这些工作可为通过星载光学传感器遥感获取船舶尾迹信息提供理论依据.试验证明在可见光和近红外波段船舶含气泡尾迹相对于背景海水的离水辐亮度、遥感反射率都不同程度地得到了增强,并且在一类水体中含气泡尾迹的光谱后向散射无论是相对增幅还是绝对增幅都要远大于二类水体中的.

| Abstract: | On the basis of the requirement of fully using remote sensing capabilities in monitoring ocean,some sea tests have been made to measure the physical and optical properties of ship wakes which contain bubbles,and to investigate how bubble populations affect the optical properties of different water bodies,such as water leaving radiance and remote sensing reflectance.These studies can provide some theoretics for capturing the information of ship wakes by the remote sensing from spectral sensors carried by satellite.These test sproved that the water leaving radiance and remote sensing reflectance of ship wakes which contain bubbles are more or less higher than the backg round waters over the visible and infrared wave bands,and whether relatively amplitude value or absolute am plitude value of the spectral backscattering of wakes with bubbles in Case I water bodies is farmore than in Case Ⅱ water bodies. |
