Ground penetrating radar (GPR) has been extensively used as a sensory system for non-destructive evaluation of transportation infrastructure. High operation efficiency is one critical specification for GPR system design. Compressive sensing (CS) coupled orthogonal frequency division multiplexing (OFDM) techniques are utilized in GPR system design to leverage the operating efficiency. OFDM technique...
In this paper a novel interpolation approach is proposed to reduce the number of samples required for system response reconstruction. We explore the effect of complex exponential term e-jkr (which is the numerator part of Greenpsilas function) in electromagnetic field, which causes the oscillation in system response especially in the high frequency domain. If it is divided from the field quantity,...
