Abstract
The inventive antenna uses a high-speed phased-array beam steering technique. By virtue of its geometry and the non-uniform power distribution throughout its many identical elements, the present invention achieves an ability to compensate for platform motion. The present invention also greatly reduces interference from low-angle antenna pattern sidelobes, notably ground- and sea-clutter. These are crucial characteristics for an accurate radar wind profiler.
