Abstract
In one aspect, a method includes representing a range of Doppler frequency offsets as a local oscillator waveform comprising a plurality of digital waveform samples, selecting a portion of the plurality of digital waveform samples using a Doppler value to form an optical heterodyne; and generating a signal associated with a target within a bandwidth of a receiver using the optical heterodyne.
