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