There are many things underground that we have no way of knowing about without previous records. The number of occupations where this poses a large problem is numerous from construction to plumbing to electrical engineering, every one of these occupations have to dig into the ground to perform a task or set the basline for a new construct. To do this they’ll first need to know where they’re digging and what they’d unearth when they do start digging. This is when it’s time to use the best method of uncovering objects underground, the ground penetrating radar.
A ground penetrating radar, similar to a ship radar uses electromagnetic pulses to detect a variety of objects, except it does this on land and in a much smaller area than your average ship radar. Made up of three different components your standard GPR equipment has a control unit, antenna and power supply all of which are on wheels and easily transportable to the desired location. The two main components are situated at the wheelbase of the device which is then pushed by the operator wiht a handle that houses the control unit that also serves as the display for the data that the radar gathers, which can also be transfered from the device to a personal computer (PC) which can then be reviewed, and a decision can be made for what needs to be done, be it repairs or removal of the discovered objects.
The process of discovering underground objects is as simple as can be, setting up the device entails placing it on the area where it has to scan. It sends electromagnetic pulses that then bounce off of the objects underground and send frequencies back up to the device’s reciever that then transforms the signals into data which can then be read by the operator or reviewed by the operator later on a PC. In many situations, a GPR equipment operator will simply note the location of a target so that it can be avoided. For these situations it may only be necessary to use a sample linescan format in order to mark the approximate area of the target on the survey surface.
This equipment is used for numerous tasks, including help with forensics, archaeology and a myriad of other occupations and tasks that require digging. The materials of the underground object also factor into the GPR’s ability to detect it. Clay, plastic, transite, metal, conduits fiber optic and anything else that hides under the ground can be detected by a GPR.
