For meeting the needs of automated real-time dynamic monitoring of heavy fog events by means of a weather satellite remote-sensing technique for specialized meteorological services like military operations and highway traffic, the paper presents a systematic study of spectral characteristics of visible and infra red light, the textures and dynamic dispersals of fogs on satellite imagery in the context of theory on the transmission of atmospheric radiation, thereby revealing their abruptness, waviness and mass-like features, which, in combination with a synthetic technique for cloud/fog maps of multi-channel remote-sensing spectra are used to set up a model for automatic separation of fogs from clouds based on the integrative application of spectral features and texture structures, for which are constructed corresponding discfiminant functions and criteria, and on this basis prepared is a"system for remotely-sensing monitoring of low cloud and heavy fog"which has been used for tests, with the main conclusions shown as follows.

本文针对军事和高速公路等专业气象服务中应用气象卫星遥感技术对大雾进行自动化实时动态监测的实际需要，从大气辐射传输理论入手，系统地研究了气象卫星遥感图像上云雾的可见光和红外光谱特征、纹理结构特征和大雾的消散动态特征，揭示了雾的突发性、波动性和团状雾特性，通过研究多通道遥感光谱的云雾图像合成技术，建立了综合应用光谱特征和纹理结构特征的云雾自动分离模型，给出了相应的判别函数和判别准则，研制了&低云大雾遥感监测系统&，并进行了实际应用试验。
