摘要
射频层析成像是一种新兴的目标定位技术,在军事、医疗和安全监控等领域有着十分广阔的应用前景。本文借鉴延伸射频层析成像理念,提出一种针对空中目标的雷达探测新技术。文章首先分析了射频层析成像基本原理,在此基础上论述了基于射频层析成像的雷达探测理念,构建了雷达层析成像探测模型,讨论了应用于大区域空中目标探测时的电磁射线构造方法,分析了雷达层析成像处理权重模型,并完成了仿真实验验证,最后对该雷达探测新技术进行了发展展望。
Radio tomographic imaging(RTI)is a new target localization technique,which has wide application prospects in military,medical,and security areas.This paper proposes a new radar technique for aerial target detection based on RTI.Firstly,the basic principles of RTI are analyzed.On this basis,the concept of radar tomographic imaging is put forward.Then,detection model for radar tomographic imaging is constructed.Electromagnetic line forming method for detecting aircraft in large area is discussed.Meanwhile,weight model of radar tomographic imaging is designed.Computer simulation results are demonstrated.Finally,the development prospects of this proposed technique are discussed.
