Remote Wind Measurement in Fog Using Laser Doppler Velocimetry.

Abstract

A Laser Doppler velocimeter is an instrument for remote sensing of atmospheric wind. This report describes a test designed to validate the ability of the laser Doppler velocimeter to measure winds in fog. The test instrument was placed at Otis AFB for a test period of one month. It was operated during conditions of fog during the test period. Three-dimensional wind components were generated using three distinct computational algorithms. A description of the laser Doppler velocimeter and computational algorithms is presented. Wind measurement results and a discussion of those results is also given. Because the laser Doppler velocimeter used for the test is a research instrument, recommendations are made for improvement for a system designed to remotely measure winds in fog. (Author)
