Abstract:
A radar system includes an electronically scanned array of dual orthogonal linearly polarized radiating elements. Each of the radiating elements is fed by a switch driven by a radar processing unit. The switch successively places each radiation element in a vertically polarized configuration and horizontally polarized configuration so that the antenna can transmit and receive both vertically and horizontally polarized images within the radar epoch/pulse timing sequence of the radar system. The vertically polarized image and horizontally polarized image are sufficiently close in time to be collated to form a multi-dimensional image. The switch may be driven at rates other than the radar system clock as dictated by algorithms for detecting weather related threats.
