Non-destructive inspection methods were developed using an ultrasonic sensor respectively based on a multi-reflected waves model and a stationary wave model, according to the difference of the magnitudes between the wave length of the ultrasonic sensor and the size of the aggregate. Also, the non-destructive inspection methods of the time domain were developed as well as those in the frequency domain, in order to ease their practical useAdding to it, an epoch-making non-destructive inspection method using an electromagnetic wave radar and an ultrasonic non-destructive inspection method of a sump pump system were developed in the extension of the ultrasonic inspection methods. To summarize them, an effective non-destructive inspection system composed of ultrasonic sensor and electromagnetic wave radar was developed to enable the detection of the defects in concrete structures

根据超声波传感器波长与骨料粒径大小的差异，分别建立了基于多次反射波模型和基于驻波模型的骨料无损检测方法。此外，为了便于实际应用，还开发了时域和频域的无损检测方法。此外，在超声波检测方法的扩展中，开发了划时代的电磁波雷达无损检测方法和污水泵系统的超声波无损检测方法。综合以上研究成果，本文提出了一种基于超声波传感器和电磁波雷达的混凝土结构缺陷无损检测系统
