Abstract
A polarimetric radar with V and H polarized array antenna elements which transmit a V component modulated by a V code and the H component modulated by an H code orthogonal thereto. Unwanted polarization errors occur at off-boresight angles, which tend to obscure the polarization characteristics of the target. Radar returns are processed to form four independent channels by convolving the signals received by the V and H antennas with the mutually orthogonal V and H codes. This overcomes the polarization obscuration and allows determination of the polarimetric ratio of the target with high accuracy.
