The Technology and Use of Ground Penetrating Radars

There are many different occupations that require the knowledge of what's under the ground, before they can start excavating, this is due to the possibility of hitting a cable, pipe or some underground object that could lead to some serious structural damage or damage to the aforementioned object that they need to dig up. By first determining the depth and location of certain objects workers can adapt to the given situation underground. And once the location is determined they can excavate with particular care to avoid damaging the cable, pipe or buried object.

Workers in fields such as construction, forensic investigation, archaeology and electrical utility have all avoided the damage that comes with digging blindly by employing the use of ground penetrating radars or GPR. A GPR can be used to create an accurate map of the subsurface, it does this by emitting pulsating electromagnetic radiation (similarly to a microwave oven) into the ground, once the magnetic energy reaches an object the object reflects that energy back to the radar which receives the energy to create a digital map of every item underground.

Not content with falling behind on the innovations of GPR Australia has GPR's that are top of the line in terms of their feature list and impressive imaging capabilities. Features that improve the ease of use and practicality of the machines such as a connection to Wi-fi which lets the user connect to google maps to determine the exact location of an underground object, a connector for smartphones, high resolution touch screens which give a clearer picture and lightweight materials for ease of use.

These features can further be improved with the various upgrades to the OS of the radar's internal computer, allowing the user to slice through the depth data, export data to computers in a variety of formats.

The hardware of a GPR can been simplified to three basic components, a control unit, antenna and the power supply. The control unit contains the electronics which trigger the pulse of radar energy through the antenna, which is always situated at the bottom of the device. Once sent the pulse returns to the antenna with the different frequencies that underground objects bounce back at a specific frequency, this is then calculated by the control unit to determine the depth and material of the object, which is then converted to readable data on the monitor and smartphone or computer connected to the device.

To conclude the GPR Australia companies use is the best non-destructive method of determining exactly what lies below the surface. It's used by many different occupations to discover the obstacles they have to tackle when excavating a certain area.
