| 1 | 基于星载SAR的海上溢油检测研究进展显示文摘基于大量有关星载SAR溢油检测研究和溢油微波散射特性研究文献的梳理和总结,回顾了星载SAR传感器的发展历程和海上溢油检测技术原理,重点总结了目前国内外基于单极化SAR数据、全极化SAR数据对溢油信息提取研究的进展,概述了溢油水面微波散射特性研究对SAR溢油检测研究的重要辅助作用及当前的研究成果,分别讨论了目前星载SAR溢油检测和溢油微波散射特性研究中存在的不足,并针对今后需解决的关键技术及发展方向进行简要分析。 | 李颖 李冠男 崔璨 | 2017 | 海洋通报2017，36，3： | 10 |
| 2 | 有限深度海域海面电磁散射的FDTD方法研究显示文摘雷达能够探测、遥感有限深度海域的海面及附近目标,针对这一需求,采用改进的文氏海谱和Monte Carlo方法模拟有限深度海域海面,选取Debye模型计算海水介电常数,运用时域有限差分法研究了有限深度海域海面电磁散射,仿真了散射系数的角分布曲线。仿真结果表明:散射系数随散射角振荡变化,在镜反射方向处产生散射增强效应;海水深度虽然对散射系数影响较小,但是仍有规律可循,海水深度越大,散射系数越小;海面风速、入射角、风区范围对散射系数影响较大,风速越大,散射系数越小;入射角越大,散射系数越小;风区范围越大,散射系数越小。 | 张童 任新成 朱小敏 杨鹏举 赵晔 | 2023 | 微波学报2023，39，2： | 1 |
| 3 | An oil slick spectral experiment of nearshore sea water in the East China Sea显示文摘Along with the rapid advance in global industrialization,oil spill events caused by offshore operations,transportation and accidents are increasing.Compared with ship surveys,monitoring oil spills through remote sensing has real-time,comprehensive,low-cost advantages,which can effectively guide cleaning and evaluation,and reduce the marine ecological destruction resulting from oil spills.Therefore,studying the remote sensing mechanism used to monitor marine oil spills is of great significance for ecological environmental protection.This paper describes an experiment and corresponding analysis based on the above-water method,using the East China Sea coastal turbid water.The analysis shows that'upward short-wave'in ultraviolet and blue-purple bands and its displacement,along with the changing thickness,are important characteristics for distinguishing between the oil slick and the sea water,and also to differentiate oil slicks of different thicknesses.From blue to near-infrared bands,the spectrum of lube oil is flatter than that of diesel,and the diesel spectrum rises faster than the lube spectrum on the right side of the trough at 400 nm.These two features form an important basis for differentiating diesel from lube oil.These analyses will further the development of oil spill remote sensing in the East China Sea. | WANG Difeng PAN Delu GONG Fang WANG Tianyu ZHAN Yuanzeng | 2013 | Acta Oceanologica Sinica2013，32，11： | 1 |
