摘　　要：应用海洋内孤立波2层流体模型的SAR遥感反演技术,对南海北部内孤立波SAR遥感反演进行了初步研究。对于不存在由同一波源生成的2个内孤立波波包的SAR遥感图像资料,可以利用Levitus等的月平均温盐资料确定跃层深度和约化重力加速度,进而确定内波波速并进行内波振幅的反演。这样能够充分利用宝贵的SAR图像资源。A preliminary study of SAR remote sensing inversion of internal solitary waves in the north of the South China Sea was made by using the two-layer fluid model of oceanic internal solitary waves. For the SAR remote sensing data in which there are no two packets of internal solitary waves excited by the same source, we utilized the monthly mean temperature and salinity data of Levitus et al. to determine the depth of the pycnocline layer and the reduced gravity acceleration, and furthermore to determine the phase speed of the internal waves and to invert their amplitudes. This method favors the full use of SAR image data.
