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...
Non-destructive evaluation (NDE) of transportation infrastructure using ground penetrating radar (GPR) is an active research subject in now days. Impulse radar is one common GPR design scheme for its simple circuit architecture. However its weaknesses include low dynamic range and high cost complicate analog-to-digital converter (ADC) requirement. Stepped frequency continuous wave (SFCW) radar overcomes...
