介绍各种成像的基本原理,列表比较微波无损检测(NDT)成像的国内外迸展。从人体与树木的相似性,将人体NDT方法应用于树木NDT的可行性作比较。介绍一种现成的微波NDT成像实验室的方案及其改进的办法。最后指出微波NDT成像原理的优点是价廉、体轻、分辨清晰。可应用于各种需要成像的不透明各向异性的具有复杂微波阻抗的被测物。
Describes the fundamentals of imaging and lists the advances at home and abroad comparing microwave non-destructive testing (NDT) imaging. From the similarity between human body and trees, we compared the feasibility of applying human NDT method to tree NDT. A ready-made microwave NDT imaging laboratory program and its improvement. Finally, it points out that the advantages of microwave NDT imaging principle are low cost, light weight and clear resolution. Can be applied to a variety of opaque and anisotropic imaging with complex microwave impedance.
