Unstable Resonator Considerations For Spaceborne Coherent Lidar Applications
SPIE Proceedings, 1989We summarize the results of an investigation into the relative merits of diffractive and radially-variable unstable resonator couplers for use in heterodyne-detection lidar systems, emphasizing overall lidar system efficiency.

Design Considerations for Spaceborne Lidars
1987Spaceborne lidars promise the capability to determine important meteorological parameters, with a height resolution and accuracy required for improved weather forecasting and understanding of the climate. Lidars can advantageously complement passive sounders due to their ability to perform depth resolved measurements with excellent vertical resolution,

LIDAR add-on for spaceborne optical communication terminals
2017 IEEE International Conference on Space Optical Systems and Applications (ICSOS), 2017Optical communication terminals consist of various subsystems that are common to LIDAR systems, i.e. for ranging and 3D surface mapping. This paper explores how to modify such a communications payload to serve as a submeter precision LIDAR, with minimum impact on complexity, power consumption and mass increase.

Wind vector retrieval algorithm from spaceborne lidar data
Acta Oceanologica Sinica, 2014The principal purpose of this paper is to extract entire sea surface wind’s information from spaceborne lidar, and particularly to utilize a appropriate algorithm for removing the interference information due to whitecaps and subsurface water. Wind speeds are obtained through empirical relationship with sea surface mean square slopes.

ADM-Aeolus: the first spaceborne wind lidar
SPIE Proceedings, 2006The Atmospheric Dynamics Mission ADM-Aeolus will be the wind lidar in orbit. The aim is to provide global observations of wind profiles with a vertical resolution that will satisfy the requirements of the World Meteorological Organization. ADM-Aeolus will carry just one large instrument-the Atmospheric Laser Doppler Lidar Instrument (ALADIN). This is

ESA Progress in Spaceborne Doppler Wind Lidar Activities
Coherent Laser Radar, 1995Space-borne global wind observation is considered a high-priority mission for the next two decades, in view of the unique benefits that operational meteorology and climate research would receive. A satellite-borne Doppler wind lidar has been recognised a potential corner-stone instrument of future wind-monitoring systems, due to its capability of ...
