摘要: 本文描述了納秒電磁脈沖在探測地下目標(biāo)中的基本方案;研制了一種高質(zhì)量行波天線。作者采用的是三層結(jié)構(gòu)的扇形天線,其輻射效率高,行波特性好。終端采用快速、高分辨率的圖形顯示系統(tǒng),對埋地深度在1m左右的金屬管道,能清晰的顯示,并打印出目標(biāo)特性。整個(gè)裝置與國內(nèi)外同類裝置相比,分辨率高,終端處理時(shí)間短,符合工程需要。Abstract: A basic scheme for detecting subsurface targets with EM pulse of nanoseconds and an especially developed travelling-wave antenna of high quality 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 burried about 1m under the earth can be detected and clearly displayed. High resolution and burried about lm under short processing time of the system, compared with other similar devices make it suitable for engineering use.
