Spaceborne laser rangefinder ranging sensitivity and accuracy analysis

摘要

Spaceborne laser rangefinder is one of the main payloads in earth observation satellites and lunar satellites. In this paper, the ranging sensitivity and accuracy of the spaceborne laser rangefinder have been discussed. And a photon counting detected mode is recommended to improve the rangefinder's sensitivity and the accuracy. A future laser rangefinder system has been designed and it's proved to be available by the test of the prototype.
