Based on the advantages of polarization technology in target detection, combination it with groundpenetrating radar measurements, we have built a fully-polarimetric GPR acquisition system, including hardware and software design, Based on the hardware matching, Using software technology to operate a single interface of the hardware, enables the system to run automatically. Used this system in the laboratory to test several typical targets, obtained the fully-polarimetric information response. View of the polarization scattering matrix can completely characterize the polarization properties of target, Calculated the polarization scattering matrix of target, Used calibration technique to remove the errors in measurements. Through the calibration of polarized scattering matrix we know that the system works well, it can be used to achieve the detection and recognition of targets, the system has good promotional value.
