An Adaptive Direction-Dependent Polarization State Configuration Method for High Isolation in Polarimetric Phased Array Radar

High cross-polarization isolation (CPI) is crucial to the accurate polarization measurement using polarimetric phased array radar (PPAR). In this article, we propose an adaptive direction-dependent state configuration ( AD 2 PSC) method improve isolation. Compared with conventional fixed of radiated wave whether it linear, circular, or elliptical state, our PSC approach configures on basis beam steering. To achieve magnitude and phase dual-polarization antenna, improved steepest descent algorithm put forward. facilitate uniform representation for application PPAR, universal expressions intrinsic measured backscatter matrices are derived arbitrary state. The dipole used assess priority proposed method. approaches, could obtain higher CPI while being available a larger scanning range. configured meets specific requirement PPAR.
