Wind Shear Requirements and Their Application to Laser Systems.

Abstract

The requirements for a ground-based wind shear sensing system are developed. System coverage, accuracy, resolution, and data update rate are treated in detail. The differing requirements for synoptic shear conditions and thunderstorm-associated shears are discussed. Several candidate sensing systems are considered. The hybrid CW/ pulsed laser is discussed in detail because of its potential for providing advance warning for all shear conditions. Propagational characteristics of laser beams are treated and equipment design implications are developed. A system concept is outlined which provides the framework for a future operational system.
