A New Scheme of Polarization Calibration Using Polarimetric Active Radar Calibrator(PARC)with Single Rotatable Antenna
摘要
Abstract
Because the far field condition of large aperture antenna is rigorous,and the effects of clutter and multi-path are sensitive,the polarization calibration for large aperture ground based radar is an urgent problem in radar engineering technical field.The dynamic polarimetric calibration(DPC)in frequency domain is a good solution to solve this problem,but the low isolation between transmit and receive antennas,as well as the asymmetry of antenna pattern,will result in the decrease of the polarization calibration accuracy.This paper designs a single rotatable dual-polarized antenna polarimetric active radar calibrator(PARC)and propo-ses a corresponding DPC method.The simulations verify that the single dual-polarized antenna DPC scheme possesses calibration accuracy better than the traditional double-antenna DPC scheme.关键词
