Assessment of Technology Requirements Associated with Spaceborne Laser Ranging. Volume 2: Theoretical Considerations and Aspects of System Realization

摘要

Long distance space to Earth range measurement systems and ground targets are discussed. Onboard data processing, and pointing subsystem requirements were derived. Range analysis demonstrates that high pulse energies are required if a YAG: Nd laser is used in a one color system. For a two color system, an alexandrite laser, and a distributed feedback dye laser with an excimer laser amplifier are feasible. A streak-tube receiver with a 20 cm telescope is assumed for signal detection. Ground target choice (solid or hollow retroreflector) depends on cost. The laser beams will not damage eyes.
