适合对称天线的平衡输出高压纳秒级脉冲源研究
资料介绍
时域脉冲源是时域超宽带雷达系统中的重要部件,时域脉冲天线大多采用对称形式,如果用非平衡高压脉冲源激励,难以实现很好的宽带匹配。为此设计了一种新的电路形式,采用平衡输出的Marx电路级联,解决了脉冲源高幅度和平衡输出不能兼顾的问题。利用与对称天线进行的纳秒级脉冲收发实验验证了该电路的良好性能。
Time-domain impulse generator is a very important unit in time-domain ultra-band radar systems.Most time-domain impulse antennas are symmetrically designed which require balanced output pulse generators in order to realize wideband matching.Aiming to solve the compatible problem of high voltage and balanced output,which commonly exists in high-voltage pulse generators,this paper designs a new pulse generator circuit,the cascade Marx circuit with balanced output.With this generator and a loaded bow-tie antenna,a 300 V nanosecond pulse was generated.The measured result validates the effectiveness of the proposed pulse generator.
