WARR – Short for Wide Area Reflection and Refraction. This is very similar to the CMP
survey described above, except that one antenna (Transmitter or Receiver) is fixed and
the other is moved away at set intervals. This can sometimes be easier where space is
a constraint, since only one antenna needs to move, however you need a more uniform
reflector than a CMP.

• Transillumination (ZOP, MOG, VRP)
Transillumination surveys are used to study the properties of a material by placing the
transmitting and receiving antennas at opposite sides of the structure. The GPR signals
travel one-way through the material from the transmitter to the receiver.
