Review on Polarimetric Phased Array Radar Technologies

Polarimetric phased array radar (PPAR) with polarization measurement capability has been the cutting-edge, high-precision radars applied by world powers in strategic areas such as missile defense and space surveillance. And PPAR is the strategic highland of military radar technology competition. More and more PPARs have been applied in antimissile defense, space surveillance, precise guidance, microwave remote sensing, meteorological observation, and other fields over recent years in China. And some systems have become benchmarks in the radar industry. This study briefly reviews the development history and system development of PPAR applied in various fields. Next, the state of the art of several key technologies of the accurate acquisition of polarization information, including the polarimetric bias correction, antenna pattern reconstruction, and polarization pattern synthesis, are summarized. Finally, the future developments of PPAR technology are considered.
