Receiver performance of laser ranging measurements between the Lunar Observer and a subsatellite for lunar gravity studies [PDF]

The optimal receiver for a direct detection laser ranging system for slow Doppler frequency shift measurement is shown to consist of a phase tracking loop which can be implemented approximately as a phase lock loop with a 2nd or 3rd order loop filter ...
