Significantly improving the resolution of Ground Penetrating Radar (GPR), is a challenging issue. Such resolution enhancement is necessary for clear imaging of closely buried targets. GPR technology has proved to be very successful in the investigation and detection of buried objects. This paper examines the possibility of applying the super resolution technique MUSIC (Multiple Signal Classification) algorithm in SFCW (Stepped Frequency Continuous Wave) GPR due to its superior performance. Additionally, the conventional FFT (Fast Fourier Transform) has been utilized for a highly precise receiving signal level. The Combined Processing Method (CPM) of time domain response of MUSIC and IFFT (Inverse FFT) has been proposed for the first time to get high resolution and high precision receiving signal level. Results of simulations and experiments show that the proposed method achieves both higher resolution, and a highly precise receiving signal level.
