Abstract:

The operational performance of the ASDE-2 radar at OHare Airport is severely limited during periods of moderate to heavy rainfall. Using the system performance specifications, an estimate has been made of the ASDE-2s tolerance to power loss and degradation of its circular polarization produced by a radome. Three aspects of the OHare radome were examined as potential sources of excessive loss. These are a the metal space frame, b the dielectric constant and loss tangent of the membrane material, and c the membrane surface properties. Author Modified Abstract
