Void detection under concrete

Post by tomwilliam »

Good morning guys!
Hoping to get some of your help in getting a better understanding of what im seing in the following radargram. The data was collected on a pier in Northern Ireland with the RIS MF HI MOD (200 and 600Mhz antenna) with the objective of detecting voids. This is the first time i've collected data with this objective in mind. I've done some research and have found that voids could have different signatures with some exhibiting ringing affect and others not.
The data displayed bellow relates to a section taken with the 200Mhz antenna.
