Abstract :
We apply a matched filter based SAR algorithm to process ground penetrating radar data. The algorithm discussed is for a stepped frequency type radar although it can be applied to other types with few modifications. The selection of the synthetic aperture length considering the ground attenuation, antenna beam pattern and the scattering pattern of the object being imaged is also discussed
