合成孔径雷达探测浅海障碍物技术实例探析

Example Analysing on Detecting Neritic Underwater Object by SAR

阐述了合成孔径雷达(SAR)探测水下障碍物的发展历程,研究了SAR的成像机理,分析了水下障碍物的SAR成像数学物理模型,并依据该模型设计了水下障碍物的通用仿真计算流程。依据浅海SAR影像资料,针对典型的浅海水下障碍物SAR成像进行模拟仿真,并将仿真的结果与真实的影像进行比较分析,证实该仿真模型具有良好的模拟仿真效果,为浅海水下障碍物的探测提供了科学的依据。

This paper expresses the phylogeny of the underwater barriers-detected based on SAR, studies the imaging principle, analyzes the underwater barriers imaging mathematical models, and designs the common simulation computing flow according to the underwater barriers. The paper invokes the fitting SAR images to simulate the typical underwater barriers imaging course,and compares the simulated result with the relevant real SAR images. The result approves that the simulation model works well and will help a lot on the underwater barriers detecting.
