叠加偏移成像技术（SMIT）是地球物理勘探中的一种先进的数据处理技术，用于混凝土结构内部小裂缝的检测。超声波传感器被用来作为驱动器和传感器，以产生和接收应力波在混凝土。利用多个换能器将损伤反射的波场合成在一个共同的反射点上，突出有效信号。分别采用水平叠加技术和衍射扫描叠前偏移技术对两个混凝土试件进行了检测。损坏的尺寸和位置被成功地成像。实验结果表明，与传统的超声检测方法相比，SMIT方法具有更好的损伤可视化效果，可以从试件的一侧进行损伤检测。
Stack migration imaging technology (SMIT), an advanced data processing technique typically used in geophysical exploration, was employed for the detection of small cracks inside concrete structures. Ultrasonic transducers were utilized as both actuator and sensor to generate and receive stress waves in the concrete. The wave field reflected from the damage was synthesized at a common reflective point to highlight the effective signals by using multiple transducers. Two concrete specimens with embedded damage were examined using horizontal stacking technology and diffracting scan pre-stack migration technology, respectively. The dimensions and locations of the damage were successfully imaged. Compared with traditional ultrasonic detection, The experimental results show that SMIT offers better damage visualization and allows damage detection from one side of the specimen.
