【摘要】 本文描述毫微秒电磁脉冲在探测地下目标中的基本理论,实施方案以及关键部件的设计,特别是高质量行波天线的研制,作者提出了一个具有独创性的方案,实践证明,辐射效率高,行波特性好。对埋地深度在1m 左右的金属管道,能快速,清晰的显示和打印目标特性,与国内外同类装置相比较,分辨率高,终端处理的时间短,符合实际工程需要。更多还原

【Abstract】 Basic scheme detecting subsurface targets with EM pulse of nancsecends,especially developing travelling antenna of high quallity are described in this paper.Authors are useing a sort of sector antenna with structure of three layers,which possesses higher radiation efficiency and better travelling properties.System of fine resolution graph and high speed display are emploied in terminal processing.Target properties of metal pipes burried about lm depth can clearly be displaied.High resolution and short processing time of the system,compared with internal and external similar device make it passable for according with the needs of engineering.更多还原
