摘　　要：典型隐身目标SAR图像仿真对SAR图像解译和目标识别具有重要意义。以国外某新型飞机为例,对隐身目标进行合成孔径雷达(SAR)成像,给出了隐身目标的SAR图像仿真结果。在此基础上,进一步研究了隐身目标SAR图像的边缘检测方法,利用边缘增强算子突出局部边缘,通过定义边缘强度设置门限法提取边缘点,进而为雷达快速识别隐身目标提供理论支持。Simulation of SAR imagery of typical stealth aircraft is important for SAR imagery interpretation and target recognition.Taking new aircraft as an example,the technology of SAR imagery simulation of Typical Stealth Aircraft is studied and realized in this paper,and the results of SAR imagery simulation of a stealth plane are given.Moreover,the edge detection method of stealth target SAR imagery is studied,Edge enhancement operators are used to highlight local edges,edge points are extractedby defining the edge strength setting threshold methods,thus provide theoretical support for fast identification of radar stealth target.
