Abstract

A method of collecting data using a polarimetric phased array antenna is described. The method includes directing electromagnetic signals to selected panels of an array of panels so as to transmit a dual H and V polarized electromagnetic beam (1) having the same beam width in all azimuth directions and (2) maintaining cross-polarization isolation via orthogonal dual-polarizations in all beam pointing directions. The panels include antennas having a horizontally (H) polarized array element and a vertically (V) polarized array element arranged to form two orthogonally polarized horizontal and vertical radiating fields which together form the dual H and V polarized electromagnetic beam. The array of panels is arranged so as to form a substantially cylindrical configuration on a support system. Reflection signals sensed by the selected panels formed by scattering of said dual H and V polarized electromagnetic beam are received and have a reflection frequency spectrum.
