Abstract :
The ranging error of short pulse optical tracking systems is investigated. The relationships between the tracker characteristics, the characteristics of the received signal and background radiation, and the measurement accuracy are determined. It is found that the effects of characteristics of the tracker, the propagating medium, and/or the target to be tracked will predominate in the derived accuracy expressions. This result is based on the assumption that the transmitted pulse duration is short compared to the delay fluctuations induced by at least one of these three effects.
