电磁涡旋波雷达研究进展

Research Progress of Electromagnetic Vortex Radar

近年来,由于电磁涡旋波雷达在超分辨率成像、目标三维重构以及旋转多普勒提取方面具有独特优势,其相关研究受到了科研人员的重视。对电磁涡旋波雷达的模态生成、目标散射特性和成像处理方法3个方面的研究现况进行系统阐述,着重介绍国内研究团队进行电磁涡旋波雷达动目标检测外场试验的相关进展,并对电磁涡旋波雷达的应用前景进行展望。

In recent years,the research of electromagnetic vortex wave radar has attracted the attention of scholars from all over the world,due to its unique advantages in superresolution imaging,three-dimensional target reconstruction and rotational doppler extraction.The mode generation,target scattering characteristics,and imaging processing methods of electromagnetic vortex wave radar are the key points that urgently need to be broken through in the application of this new system of radar.Therefore,in this paper,we systematically describe the research situation of these three aspects of electromagnetic vortex-wave radar,and focus on the relevant progress of the field test of electromagnetic vortex-wave radar in moving target detection in the world,and finally look forward to the application prospect of electromagnetic vortex-wave radar.
