摘要
针对紧缩场成像系统造价昂贵,设计了一种新的近距离微波成像系统。采用合作目标建立数字建模,推导了严格的成像公式,应用球面波滤波-逆投影算法进行快速求解。仿真结果表明,该系统实现简单,能在球面波照射条件下获得雷达目标的高分辨率二维像,准确地诊断出目标的散射点分布,具有很高的推广应用价值。
For the purpose of expensive cost on the comp, a new near-distance diagnosing system is designed. The theoretical formulation of imaging can be gained by mathematic modal with cooperation object. Imaging formulation can be solved by spherical wave fiher-antiprojecting arithmetic quickly. The simulation result show that good performance 2-D image with high resolution can be obtained by utilizing spherical filter-antiprojecting arithmetic,which can digest the scattering points exactly and in detail.
