Design Study of a Laser Radar System for Spacelight Application.

Abstract

This report provides the analyses of several laser measurement techniques for the determination of the density of the neutral atmosphere from space. Several operational concepts of a laser radar system for spaceflight applications were investigated, including also, a proof-of-concept balloon-based experiment. The recommended baseline density measurement technique uses two wavelengths and the wavelength dependence of Rayleigh scattering (1/lambda to the 4th power) and Mie scattering (about 1/lambda) to separate the neutral atmosphere returns from those of aerosols and particulates.
