伪随机二进制序列探地雷达主控系统设计

Design of Deep-scale GPR Host Control System with PBRS

提出了利用伪随机二进制序列(PRBS)实现深层探测的探地雷达主控系统的设计方案,同时完成了该主控系统的硬件设计任务。主控系统由单片现场可编程逻辑阵列(FPGA)来实现,集成度较高。通过实验验证,该主控系统能够完成系统发射信号产生,定时信号产生,回波信号采样,数据传输,参数控制等功能,满足设计指标要求。

The design scheme of deep-scale Ground Penetrating Radar host control system with Pseudo Random Binary Sequence is proposed. Meanwhile, the hardware of the host control system is designed, simulated and implemented. The host control system is implemented by single Field Programmable Gate Array, so it has a high-level integration characteristic. The system has been tested by experimentation, which could produce transmitting signal, generate timing signal, sample the echo signal, transfer data to PC using USB and control the parameter, et al. Therefore it satisfies the desire of design target.
