| Abstract: | Basic scheme of detecting subsurface targets with EM pulse of nanoseconds, especially the design of travelling wave antenna of high quallity are described in this paper. The antenna is of three layers in structure, which possesses higher radiation efficiency and better travelling wave properties.Fine resolution graph and high speed display are employed in terminal processing. Target properties of metal pipes hurried about 1m depth can be clearly disp-layed. High resolution and short processing time, compared with internal and external similar devices, make it possible to meet the needs of actual engineering. |
