【摘要】 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。更多还原

【Abstract】 Submerged moving bodies may present some wake features on ocean surface. These features are various from different parameters of moving bodies, different depth of submergence and different sea-states. It is probably using Synthetic Aperture Radar (SAR) to detect submerged moving body through studying these wake features and its imaging by SAR. In this paper we present the fast simulation of submerged moving body’s wake features on ocean surface and the simulation of wake features imaging by SAR. Some simulating examples are presented and discussed in the end of the paper.更多还原
