Meteorological Radar Facility for the Space Shuttle

Abstract

A proposed meteorological radar facility for Space Shuttle missions is described as a device suitable for providing vertical profiles of the precipitation distribution in the atmosphere above land masses and over ocean, thus ensuring three-dimensional mapping of the hydrometeor-precipitation distribution in the atmosphere. Some performance characteristics essential to orbiting meteorological radar systems and typical parameters are discussed, including large swath width, narrow beamwidth, frequency agility, and antenna configuration and orientation. Also discussed are the capabilities of the device as a test bed sensor with multiple mode capability, being able to operate in real aperture/pulse radar, real aperture/pulse Doppler and synthetic azimuth processing modes.
