Knowing which GPR system to use for a given application can be a daunting task, especially for a new user. Our latest infographic series aims to simplify the selection process by highlighting two key criteria: depth range and resolution.
In simple terms, the lower the center frequency of the GPR antenna, the deeper the signal can penetrate, but at the expense of resolution in the shallower layers. Higher frequencies offer better resolution in shallower layers but don’t penetrate as deep. Also, the size of the detectable object varies with depth. Small objects can be seen at shallow depths, but as the depth range increases, so must the physical size of an object to enable detection.
Of course, there is a much more complicated theory behind this, but these basic rules apply. As always, the dielectric properties of the ground under investigation will determine the performance and success of GPR measurements.
