Abstract


The ancient building is a witness of the development of human history , is a living history of the kind . The ancient building protection has an important meaning for us this ancient civilization has a long history and culture . However , the detection of the work of the ancient building is probing the ancient building without destroying the premise , to ascertain the structure and potential pitfalls . The GPR method is the use of a high-frequency pulse electromagnetic waves to determine the target within the material and distribution law geophysical methods . Its detection speed fast, high- resolution , no damage to detect objects , the characteristics of continuous imaging information can be applied to the nondestructive detection in the ancient , ancient protection of the ideals of the early investigation , as the ancient architecture protection to provide a scientific basis for the actual value and significance . This paper Dengfeng Observatory to detect instances of ground penetrating radar in ancient nondestructive detection , data processing and analysis , pointed out the structural composition and potential pitfalls of stargazing . This article is specific to complete the work and research are as follows : 1 , based on the principle and characteristics of the GPR method to study the ground-penetrating radar nondestructive testing technology in all aspects of the ancient building applications , data acquisition , data processing and data interpretation . 2 , the completion of the the Dengfeng Observatory of field data collection , data processing , process optimized the Dengfeng Observatory data processing . To Dengfeng Observatory for the study of the obtained radar detection data processing and analysis , and to determine its internal structure and composition . 4, the comprehensive analysis of the Dengfeng Observatory ground-penetrating radar data and the internal structure of the analysis and recognition, and summarizes its characteristics in the time profile of the possible presence of hidden cracks, voids , for the future of the ancient probe work to provide a certain basis . Ground penetrating radar technology are better able to provide a reliable scientific basis for the ancient protection . Due to the characteristics of ground penetrating radar , ground penetrating radar technology in ancient architecture will NDT play an increasingly important role .
