Research of P band circular polarization SAR

For space-borne P band Synthetic Aperture Radar (SAR) application, an airborne experimental circular&linear polarimetric SAR system is developed, this paper presents the instrument and airborne test result. Compared to linear polarization of P band, circular polarimetric SAR shows remarkable penetration efficacy in tropical jungle foliage covered region and subsurface targets detection. Besides, A new phenomenon of P band circular polarimetric SAR implies potential advantage in man-made linear object detection.
