摘要: 研究设计了一种0.2 THz的步进频率雷达成像系统,带宽12 GHz,并利用逆合成孔径技术对物体进行二维高分辨成像。针对系统设计参数进行Matlab仿真,获得简单转台目标的二维逆合成孔径雷达图像。仿真结果表明,太赫兹雷达成像系统可实现目标的二维高分辨成像,横向和纵向距离可以达到cm级分辨率。Abstract: A 0.2 THz stepped frequency radar imaging system with 12 GHz bandwidth which uses inverse synthetic aperture to realize two-dimensional high resolution imagery is proposed and designed. The results of Matlab simulation based on system design parameters show that the THz radar imaging system could realize two-dimensional high resolution imagery of the target, and the horizontal and vertical distance can reach centimeter-level resolution.
