The Design and Implementation of FPGA-based Deep Ground-Penetrating Radar Host Control System

The Ground Penetrating Radar (GPR) is a technique that utilizes the radio waves to map structure and features of objects buried in the ground. In this paper, we design a host control system (HCS) of GPR based on a maximum length binary sequence, abbreviation M-sequence, to implement the detecting of deep level objects on earth, and we realize the design of software and hardware for the HCS of GPR. Using single field-programmable logic array (FPGA) as the core, the HCS improves the flexibility of the system, reducing power consumption. Experiments show that the HCS can complete the tasks of generating transmitting, echo signals sampling, data transmission, controlling the work modes with parameters, meeting the design specifications requirements.
