| 摘要 |
A ground penetrating radar (GPR) system (1) and a method of detecting a feature (9) embedded in a solid or liquid medium (10) from outside of that medium are disclosed. The GPR system comprises a transmitter (2) for generating and transmitting a radar signal (8) towards the solid or liquid medium comprising the feature, and a receiver (3) for receiving the radar signal after reflection on the feature, the transmitter comprising a signal generator (4) and at least one magnetic dipole antenna (5). The receiver comprises at least one magnetoresistive sensor, which is used to detect the reflected radar signal. |
