The Impact of Vibration on TNR for a GPR System

In this paper, we analyze the effect of vibration on B-scan image quality for ultra-wideband (UWB) ground penetrating radar (GPR) systems. Specifically, we consider the target to noise ratio (TNR) specification for each B-scan taken, comparing it with a control setting with no vibration. The vibration frequencies are 10 Hz, 27 Hz, and 37 Hz. Compared to the non-vibrating condition, TNR is reduced by at least 3.75 dB in each vibrating scenario. Among all different vibration settings, the TNR values stay within 0.71 dB of each other.
