Abstract
A basic scheme for detecting subsurface targets with nanosecond EM pulse and an especially developed high quality travelling-wave antenna are described. The antenna is a sort of sector antenna with structure of three layers, which possesses higher radiation efficiency and better travelling-wave properties. A fine resolution graphic system and a high speed display are employed in terminal processing. Metal pipes buried about 1 m under the earth can be detected and clearly displayed. High resolution and short processing time of the system, compared with other similar devices, make it suitable for engineering use.
