摘要
提出了一种基于等效时间采样方法的冲击型探地雷达回波信号高速采样系统,设计实现了等效时间采样的关键电路,包括步进采样脉冲发生器、采样门电路。实验证明了使用该方法采样回波信号的有效性。
A high-speed sampling system for echo signal of impulse GPR based on equivalent time sampling method is presented, and significant circuits including step sampling pulse generator and sampling gate circuit are designed. The experimental result proves that this sampling method for echo signal is effective.
