A cross-correlation envelope method which generates a model fitness from a reflected wave
is used as pre-process for an image reconstruction. The range of the model fitness is …

Optical fiber cable for the broad bands communication is usually covered by plastic pipe and
buried under the ground. Then, we are required to grasp its real buried position before …

We fabricated a position surveying system for underground pipes using two rotary encoders.
Two rotary encoders measure distance of right and left walls of the pipe. It was confirmed …

In this report, a novel signal and image processing method for microwave subsurface radar
is proposed, which enables to estimate the internal construction in concrete structures. By …

抄録 For a safety diagnosis of RC structures, a microwave radar method has advantages on
a nondestructive inner inspection. In this report, novel processing techniques for the …
