A low-cost handheld integrated UWB radar for shallow underground detection

In order to fit the demands of low cost and miniaturization for ground penetrating radar (GPR), a handheld integrated high resolution UWB GPR system was developed. The design methods of the low-cost RF module with the impulse transmitter, the sequential receiver and the UWB antenna were described, and the structure of the embedded control module with the radar control unit, the data acquisition and the image process unit were also introduced. The integration improves the convenience and the stability of the system. Several experiments were carried out with the prototype. The experimental results show that the system could detect shallow underground objects effectively with high resolution.
