| 摘 要： | 脉冲超宽带雷达发射信号为窄带信号,回波信号带宽很大难以直接采样,文中设计了一种以FPGA作为控制器的超宽带(UWB)雷达信号采集与控制系统。根据回波信号呈周期性的特点,实现了时域延时式等效采样。为了使雷达主机与PC机之间实现高速通信,设计了USB 2.0接口电路。实验结果表明,该控制系统等效采样速率可达5 GS/s,可以有效的接收雷达回波信号,并且能检测到人体教具的位置和呼吸频率。

| Abstract: | Ultra-wideband radar pulses transmitted signal is narrowband signal, the echo signal bandwidth is greatly difficult to directly sample, this paper designs a Ultra-wideband Radar Control System Based on FPGA. According to the characteristics of the echo signal periodically to achieve a delay-type time-domain equivalent sampling. In order to achieve high-speed communication between the host and PC radar designed USB 2.0 interface circuit. Experimental results show that the control system can achieve 5GS/s equivalent sampling rate and detect the position and respiratory rate of teaching aids. |
