Multi Channel GPR

Multi-channel GPR systems use a mobile array of multiple GPR antennas mounted on a cart-based GPR unit, which is typically towed behind a vehicle during survey operations.


Others: IDS Georadar Stream UP GPR, Proceq GP8100, kontur DEEP 1808

One example for instance, consists of 17 GPR antennas positioned in two overlapping rows of 9 transmitters and 8 receivers. This 58 system is collecting 16 channels of densely spaced GPR data. 


GPR imaging with multi-channel systems has greatly improved the areal coverage of the ground. Along with improved imaging software, datasets recorded with multi-channel systems can be processed at similar speeds to coarsely spaced single channel data that would normally require additional time for interpolation processes to fill in the gaps between lines. Case studies of implementation from several different multi-channel GPR systems are shown below.
