摘　　要：研制出一种用于超宽带短脉宽辐射和接收的新型集成超宽带（ＵＷＢ）槽天线，该天线采用共面波导到槽线的宽带过渡方式馈电，实验结果显示了其高保真的宽带特性及高增益高效率特性．利用所研制的ＵＷＢ天线建立起超宽超带雷达（ＵＷＢＲ）实验系统，测量几种简单目标特性及涂层目标特性，证明了该种天线可用作实际的ＵＷＢＲ天线．A novel plane integrated ultra-wide band(UWB)antenna used as the radiation andreception of the short pulse is developed. A new UWB feed structure of the coplanar waveguide toslot line is invented and used in slot antenna initially. The experimetal results show the advantageof high fidelity of the waveform,high radiating efficiency, and high antenna gain compared withsome common wide band antennas such as biconical antennas,V-conical antennas,and some otherTEM horns.
