描述了一种相干合成孔径雷达（ＩＮＳＡＲ）Ｋｅｌｖｉｎ航迹（舰船航迹）成像的数学模型，对一定条件下Ｋｅｌｖｉｎ航迹的相干合成孔径雷达成像进行了计算机仿真。该模型以运动舰船在海面所产生的速度场作为输入，对研究舰船航迹在相干合成孔径雷达图像中的成像机理提供了理论分析依据
A mathematic model of imaging Kelvin track (ship track) of coherent synthetic aperture radar (INSAR) is described. The coherent SAR aperture imaging of Kelvin track under certain conditions is simulated by computer. The model takes the velocity field produced by the moving ship on the sea surface as an input and provides a theoretical analysis basis for studying the imaging mechanism of ship track in the coherent SAR image
