TDWR Scan Strategy Implementation
Abstract
The Terminal Doppler Weather Radars (TDWRs) installed at major airports around the country are intended to enhance the safety of air travel by the detection and timely warning of hazardous wind shear conditions in the airport terminal area. To meet these objectives, scan strategies to efficiently cover the protected airspace were developed after extensive testing at several sites with different meteorological environments. Since the topology and geometry differ at each TDWR location, special considerations were necessary to define the specific scan sequences for each site. This report describes the criteria used to establish these scan sequences, including the determination of the lowest practicable elevation angle for each site - the 'surface scan,' which is used to detect microburst surface outflows, and other special scans such as the 'MTS scan,' which is used to illuminate the remote Moving Target Simulator (MTS).
