基于嵌入式雷达回波采集电路设计与实现

Design and Implementation of Pulse-echo Acquisition Circuit for Through-wall Radar based on FPGA

本文应用等效时间采样工作原理,设计了一种基于FPGA实现的穿墙雷达高速窄脉冲采集电路,电路结构简单可靠。测试结果表明,采集到的回波脉冲波形与发射脉冲基本相同。

Applying the principle of equivalent-time sampling, this paper designs a fast narrow pulse acquisition circuit for throughwall radar, based on FPGA. The circuit is simply-structured and reliable. The result of the test shows that, the acquired pulse echo is mainly the same with the transmitter pulse.
