摘要：
Deterioration of pavements or tunnels results primarily from the existence of voids under the pavements or tunnel linings. To detect these voids effectively by non-destructive tests, a method using radar was proposed. In this research, it is investigated to detect the shape of voids by radar image processing. The experiments were conducted to detect voids under concrete slab. From the results, the fundamental algorithm for tracing the voids, improving the horizontal resolution of the object image and detecting shape of objects, was verified.
