Abstract
An active receiver having a digital-pixel focal plane array (DFPA) ranges a target when observing return pulses from a pulsed laser beam synced with the receiver. The DFPA establishes a time when the pulsed laser beam contacts a target and the range can then be established because the speed at which the laser beam travels is known. Various basis functions may be implemented with the DFPA data to establish when the laser beam contacts the target. Some exemplary basis functions are binary basis functions, and other exemplary basis functions are Fourier basis functions.
