What is GPR?
Ground-pentering radar (GPR) is a geophysical strategy, which is uses pulses to record a response in the means of a picture showing the subsurface area.(Beneath the soil). Ground pentering radar uses its radio magnetic radiation with the microwave band of Radio Spectrum. It shows the reflected results came from the subsurface. It could be used in a vast usable field such as rock,soil,ice,fresh water , pavements and structures.
HOW GPR Works?
Ground pentering radar uses magnetic radiations, it leaves a high frequency beneath the soil. Through GPR we can find out the elements beneath the soil as the frequency is fired beneath the soil whenever it detects an elements, the element returns the same amount of frequency or in a less of frequency to the GPR. If the frequency is as same as it was sent it means the object is buried near only and if the frequency comes back with low or less amount that means the object is far below the surface.
GPR takes two things into consideration when preparing for the results, it considers time as well that in how much time does the frequency returned to us back , and the second point which is considered is the amount of frequency returned which we have already discussed above.
HOW GPR show its results?
After getting all the responses from all the considerations taken it shows a graph picture basically which is in the shape of a line in which there are several lines upward sloping lines which shows the object’s position beneath the soil. Data may be presented as three-dimensional blocks, or as horizontal or vertical slices. Horizontal slices (known as "depth slices" or "time slices") are essentially planview maps isolating specific depths. Time-slicing has become standard practice in archaeological applications, because horizontal patterning is often the most important indicator of cultural activities.
