摘要/Abstract

摘要： 针对一个射频体目标的不同观察面,给出两种近场辐射断层成像的二维成像算法。在利用FEKO模型进行仿真并导出近场数据的基础上,对模型的横断面和冠状面分别进行二维近场辐射成像。通过改变近场扫描点数以及接收天线与模型距离等参数,研究了不同变量对成像分辨率的影响。在对仿真计算结果进行分析之后,将本算法与其他成像算法进行比较,探讨了各自的优势与局限性。最后将算法扩展到应用层面,研究了真实场景中存在干扰物体情况下成像的变化及相应的解决方案,使研究具有一定的实际应用价值。

Abstract: Two two-dimensional imaging algorithms of tomography are presented for observing different sections of RF objects. Two-dimensional images of the cross and coronal sections of the model are obtained based on the near-field radiation data calculated by FEKO. The effects of different variables on the imaging resolution are studied by changing near field scanning points and distance between the observation plane and RF objects. After the analysis of the simulation results, the proposed algorithms are compared with other imaging algorithms from different aspects. The advantages and limitations are discussed. The change of images and the corresponding solution are studied under the presence of interference objects, so that the research has certain practical application value.

Key words: near-field radiation, two-dimensional imaging, FEKO, coronal plane, cross plane
