Abstract

We have analyzed the feasibility of measuring the global wind field from orbital altitudes to 800 km using a coherent infrared lidar. A one-meter diameter telescope is assumed on the satellite, collimating the 10 J pulses that are 3-7 µs is in duration from a CO2 TEA isotope gas laser. The lidar scans in a conical pattern around the nadir point in 11 s while pulsing at an average rate of 8 Hz. A comprehensive computer simulation that includes lidar, platform, and processor characteristics and atmospheric effects indicates that it should be possible to measure global winds at 1 km height intervals throughout the troposphere with an accuracy of 1-2 m s-1, so long as dense clouds do not obstruct the line of sight. A conceptual design for a Space Shuttle feasibility demonstration lidar has been completed.
