GPR Signal Strength

Can I tell what type of target I have by the GPR signal strength?

GPR signal strength is survey dependent and the simple answer is no.  This is because the same object can give different signal responses depending on different factors. GPR signal strength or amplitude is not specific to just a type of target. Signal strength is based on several factors: electrical contrast, object size/orientation, and signal absorption (subsurface conditions). The electrical contrast between materials …

GPR Survey Time Estimate

GPR Survey Time can be Estimated

The GPR survey time is only a guesstimate but it is better than nothing. According to Sensors & Software, manufacturers of ground penetrating radar, there are several variables to the speed of a survey. The biggest factor is collection speed, which is most affected by terrain and obstacles. Obviously, a survey over a groomed golf course will go quicker than …

GPR to detect coins

Can I use GPR to detect coins?

GPR detects metal. Can I use GPR to detect coins? This is a common question! The answer is, it depends. In most instances, individual coins are too small to be detected.  Often, there is not enough of a GPR signal reflected from the object because the station intervals are too large or the frequency of the antenna is too low to …

GPR target directly below another target

Can I find a GPR target directly below another target?

  Multiple GPR targets may or may not be located. If one GPR target is spaced beneath a second GPR target, it may be possible to record energy that is reflected back as the system approaches and passes the lower object. Otherwise, the shallower object will likely need to allow some of the ground penetrating radar signal to penetrate through …

Noggin Verses PulseEkko

pulseEKKO PRO verses Noggin

  pulseEKKO PRO verses Noggin, both are winners. The biggest difference is the pulseEKKO PRO’s flexible design with different transmitters, receivers, antennas, and control units  This means that the pulseEKKO PRO has the ability to do more advanced GPR methods that require different configurations such as a CMP or transillumination survey, which require independently movable antennas. The pulseEKKO PRO can be …
