| 摘要: |
| 运用切割式巴仑实现高功率超宽带天线的平衡馈电，并用FDTD进行仿真分析。研制出2×4元高功率天线阵，测量结果显示该天线阵能耐250kV以上高压，工作带宽达6个倍频（200～12 000MHz），具有较好的脉冲波形保真性。利用所研制的天线阵列建立外场探测实验系统，在外场进行目标探测试验。结果表明该天线阵可以用于实际的超宽带雷达发射天线阵，为高功率源在雷达探测中的应用作出了初步探索。 |

| Abstract: |
| The split-tapper Balun was introduced in the high-power ultra-wide-band (UWB) antenna. Finite-difference time-domain (FDTD) was used to analyze the Balun and antenna. The 2×4 elements array was fabricated and the measurement result shows that the antenna can resist high voltage up to 250kV with six multiple frequency (200～12 000MHz) and preserves short pulse waveform well. Outdoor detection experiment system was built by using the antenna array. Target detection experiment was carried outdoors. The experiment result indicates that the array can be used in the practical UWB radar for transmitting antenna arrays, thus making a first step for the application of high-power source in radar detection. |
