چکیده انگلیسی
With the aid of vector network analyzer (VNA), a relatively simple polarization scattering matrix (PSM) measurement system is constructed in an anechoic chamber. Four antennas with different polarization are connected for dual-channel measurement, then the PSM parameters and the frequency-amplitude characteristic can be obtained, finally the calibration is completed with three known model, with the help of metal disc, a vertical dihedral and a dihedral rotated at 22.5°, a polarization scattering matrix of a ball is measured in the experiment, The results show that polarization purity of the system reaches 25 dB without calibration, and can be better than 40 dB after that. Moreover, the system is easy to achieve.
