Focused algorithms for ground penetrating radar imaging

The paper describes the simulation results for a ground penetrating SAR radar. As a simulation model of SAR system the pulse radar with LFM (Linear Frequency Modulation) signal has been applied. The aim of the experiment was to test ability of the SAR system to obtain fully focused image of the underground targets. Simulation results presented in the paper are the first step of realization of the project of GPR (Ground Penetrating Radar) demonstrator which is conducted by Przemysłowy Instytut Telekomunikacji S.A. in cooperation with Warsaw University of Technology. In the next step, the real data measurements are planned to be performed. During measurement campaign the GPR SAR demonstrator mounted on the rails wagon will be used to generate radar motion.
