【摘要】 在研究水面油膜微波辐射测量理论的基础上,利用污染水面的多层介质模型分析其电磁特性,依据等效传输线模型分别获得水面和油膜的辐射亮温,建立起亮温对比度与油膜厚度的对应关系。根据3mm、8mm波段下亮温对比度与油膜厚度的一一对应关系,有效的获取了水上薄油膜厚度信息。更多还原

【Abstract】 Measurement theory of the surface film of microwave radiation has been studied.The water electromagnetic properties have been analyzed with the help of multilayer dielectric model.Brightness temperature of the oil film and water is obtained in the based on equivalent transmission line model.The relationship between brightness temperature contrast and the film thickness is established.The film thickness information can be obtained according to the correspondence between brightness temperature contrast and film thickness on the 3mm&8mm band.更多还原
