Abstract
Ladar systems are provided. An exemplary ladar system includes a waveform generator for generating an arbitrary waveform, a laser for transmitting a modulated light signal toward a target, and a Doppler tracking loop for tracking the Doppler frequency shift between the transmitted light signal and a received reflected light signal.
