水下物体运动引起扰动 ,会在海面产生尾迹。这种尾迹特征同运动物体的参数和下潜的深度以及海况有关。研究这种尾迹特征及其合成孔径雷达 (SAR)成像 ,就有可能利用SAR来检测这个水下运动物体。本文给出了一种水下运动物体的伴流尾迹的快速模拟方法及其合成孔径雷达 (SAR)成像仿真方法 ,并对模拟仿真的结果进行了讨论。 Underwater objects caused by disturbance of movement, will have a wake on the sea. This wake feature is related to the parameters of the moving object, the depth of the dive, and the sea state. To study this wake feature and its synthetic aperture radar (SAR) imaging, it is possible to detect this underwater moving object using SAR. In this paper, a fast simulation method of wake wakes of underwater moving objects and its synthetic aperture radar (SAR) imaging simulation method are given. The simulation results are also discussed.
