摘　　要：为采用卫星遥感数据反演的方法获取水下潜行器的光学隐蔽深度,实现时间和空间上大范围、大尺度的测量,为水下航行器搭载的光学隐蔽深度测量装置提供新的校验途径,提出了一种基于准分析算法的光学隐蔽深度卫星反演方法。根据光学隐蔽深度模型,使用Aqua-MODIS以及Terra-MODIS卫星的日网格化遥感反射比数据,先对数据进行预处理,完成遥感反射比数据的质量控制和Aqua、Terra卫星数据的交叉校准,再根据准分析算法和Doron算法建立卫星反演光学隐蔽深度模型,制作特定海区光学隐蔽深度融合产品。在模型中输入443,488,555nm波段的遥感反射比数据,数据等级为L3m,空间分辨率为4km,数据的经度范围为100°E^125°E,纬度范围为10°N^38°N。结果表明:基于准分析算法的光学隐蔽深度卫星反演技术路径可行,开拓了光学隐蔽深度获取的新方式,为水下光学隐蔽深度测量装置提供了校验方法,并为水下光学隐蔽深度相关探测与反探测等军事应用提供了重要的理论支撑。In order to obtain the optical concealment depth of underwater submersible by satellite remote sensing data inversion and realize large scale measurement in time and space,we propose an optical concealment depth remote sensing inversion method based on the quasi analytical algorithm（QAA）.At the same time,it is a new way for underwater vehicle equipped with the optical concealment depth measuring device.According to the optical depth concealment model,Aqua-MODIS and Terra-MODIS satellite remote sensing reflectance data is used on the grid.After preprocessing the data,the remote sensing reflectance cross calibration data quality control is completed,and the Terra and Aqua satellite data is cross-corrected.According to quasi analytical algorithm and Doron algorithm,the optical concealment depth remote sensing inversion model is established.The optical depth concealment fusion product for specific sea area is made.Three bands remote sensing reflectance data of 443 nm,488 nm,and 555 nm is inputted for the model.The data level is L3 m,and spatial resolution is 4 km.The longitude range of data is from100°E to 125°E,and the latitude range is from 10°N to 38°N.The results show that,based on quasi analytical algorithm,optical concealment depth remote sensing inversion technology is a feasible path.A new method to obtain optical depth concealment is developed.The method provides a calibration method for underwater vehicle equipped with the optical concealment depth measuring device,and it also provides important technical support for underwater optical depth detection and anti-detection and other military applications.
