摘　　要：溢油是海洋环境的主要污染源之一,及早监测与发现对保护海洋生态环境具有重要的价值与意义。针对溢油散射机制问题,通过分析基于波浪谱溢油后向散射系数计算研究,综合考虑水体特性、水分子张力、弹性模型及表面张力等因素的研究状况进行了分析,对针对微扰近似解方程,结合水体参数的阻尼作用的研究开展了综述,阐述溢油遥感监测阻尼在与波浪谱结合不紧密以及阻尼的定量计算不够等研究不足问题,并提出了今后溢油遥感监测阻尼的研究在针对海浪谱的阻尼特性、基于波浪谱后向散射系数计算的研究方向,为定量分析溢油的阻尼特性提供技术支撑,从而提高溢油遥感监测的精度。Oil spill is one of the main sources of pollution to the marine environment.Early monitoring of oil spill is very important for marine environment protecting.In this paper,the calculation of radar backscattering based on the wave spectrum was carried out,and a review of the study of the damping ratio of wave spectrum in consideration of the films characteristics,water molecular tension,elastic model and surface tension was carried out.The problem of insufficient research on the damping of the oil spill remote sensing monitoring with the wave spectrum and the quantitative calculation of the damping was discussed.The research on the damping of the oil spill for remote sensing monitoring in the future may be based on the backscattering characteristics of the real ocean wave spectrum under the cover with oil slicks.The research on radar coefficient calculation can provide support for quantitative analysis of the damping characteristics of oil spills,thus improving the accuracy of oil spill remote sensing monitoring.
