【摘要】 探地雷达无损检测技术在过去的十几年中无论从理论还是应用方面都产生了巨大的进展,所以对这项技术进行回顾与评述具有重要意义。首先对探地雷达的应用过程进行了一定的回顾;然后从理论角度,讨论了探地雷达正演方法的优缺点;最后对探地雷达中的参数反演问题进行一定的评述,并主要针对参数反演问题中的局部极值问题,讨论几种目前比较有效的方法。更多还原

【Abstract】 Over the past decade,nondestructive testing techniques of Ground Penetrating Radar(GPR) have made the great progress on the theoretical and practical aspects,therefore,this review is of interest.Firstly,the practical applications of GPR are introduced.Secondly,from the point of view of theory,the advantages and disadvantages of the forward methods for GPR are discussed.Finally,the issues of the coefficient inverse problem for GPR are commented,as well as some numerical methods for the local minimum in the field of the coefficient inverse problem are compared.更多还原
