Study on Polarimetric measurement and radar target identification in instantaneous polarization radar system

Instantaneous polarization radar can obtain radar target polarization scattering matrix (PSM) by taking advantage of single pulse echo signal. The polarimetric measurement properties and weak target detection of this system is verified by external field experiment. The actual measured data is used to target classification by applying polarization statistical properties and transformation of target polarization scattering matrix or decomposition. Two different radar target identification subject to its polarization properties has been demonstrates the effectiveness of using polarimetric data and motivates the use of polarimetry for target detection in clutter and interference environment. The back-scattering power and optimized transmission polarization of the system is also involved.
