Abstract
A Semi-Active Laser sensor for determining a line-of-site to a target includes: a receiver for receiving a plurality of target pulses; a processor for starting a target track for pulses that cross a noise threshold opening a pulse gate within the target track; and for every laser pulse received within the pulse gate crossing the noise threshold, determining a time index relative to the pulse gate center; and a memory for storing the pulses that cross the noise threshold and their respective time index, wherein the processor further temporally offsets the stored pulses based on their corresponding time indexes, sums the offset pulses together to generate a summed pulse signal, and determines the line-of-sight error to the target from the summed pulse signal.
