On the Scan Performance of Phased Array Fed Cylindrical Reflector with SuperQuadric Projected Aperture: PO/FFT Analysis

Abstract

The need for enhanced observational capabilities in a spaceborne microwave radar instrument to measure rainfall rates, vertical velocities with precipitation, and latent-heating profiles accurately and at sufficiently good resolution and spatial coverage throughout the tropics and mid-latitudes requires a large antenna with high-performance beam-scanning capabilities to avoid contamination by the surface clutter known as range ambiguity.
