摘要:
针对雷达波在介质中的传播特性和衰减特性,建立了雷达信号在混凝土介质中传播和衰减的数学模型; 基于探地雷达的工作机理,提出了对被接收的雷达反射波信号的衰减进行补偿,并且给出了衰减补偿公式。采用该方法对存在裂缝、孔洞和混凝土不密实区域的混凝土构件进行雷达无损检测,经过对雷达信号数据进行衰减补偿后,再对数据进行成像处理以获得雷达扫描图像。结果表明,扫描图像可以较为清晰地显示混凝土构件深部中的缺陷,与工程实际情况符合良好。
Abstract:
According to the characteristics of diffuse and attenuation of radar wave in medium, the mathematical model of diffuse and attenuation of radar signal in concrete medium was established. Based on the work mechanism of radar wave, a formula about compensating the attenuation of the reflecting radar wave signal was presented, and an attenuation compensation formula was given. By image processing on the radar testing data compensated with the method, the radar scanning images were enough clear-cut to display defects in inner concrete, such as the crack, void, incompact zones and so on. It is illustrated with the radar images in practice, which displays the same fabric as the detected inner concrete member with damages. As a result, the method brings radar scanning images into accord with practice.
