Providing subsurface imaging solutions with non-destructive and eco-friendly technology
Ground Penetrating Radar
Ground Penetrating Radar (GPR) is a geophysical technique that is widely used to study the shallow subsurface in a broad range of applications and environmental settings. GPR is a non-destructive and non-invasive geophysical method that uses radar pulses to image the subsurface and detect reflected signals from subsurface structures. GPR is widely used to locate underground utilities in the civil engineering and construction industries. It provides accurate mapping of existing underground utilities with real time visualization which provides immediate answers to facilitate efficient decision making.
GPR Principles
GPR uses short impulses of high frequency radio waves directed into the ground to acquire information about the subsurface. When the waves hits the buried object or a boundary with different dielectric constants, the receiving antenna records the variations in the reflected return signal. The depth and resolution that can be achieved with GPR depends on the frequency of the transmitted electromagnetic pulse. A higher frequency results in higher data resolution, whilst a lower frequency results in better depth penetration.
