Abstract

Ground penetrating radar (GPR) using electromagnetic pulse requires high resolution due to its narrow bandwidth nature. The rising requirement for high resolution lead to specific demands for improved prediction methods, all requiring many aspects to be examined. The application of the super resolution method MUSIC (multiple signal classification) algorithm and FFT (fast Fourier transform) are examined. The combined processing method (CPM) of the time domain response of MUSIC and IFFT (inverse fast Fourier transform) is proposed for signal processing of GPR for the first time. Simulation and experimental results show that CPM has both higher resolution and higher receiving signal level than other conventional signal processing methods
