Abstract : Pulse returns received as discrete range samples are averaged, summed with each new range sample and stored individually in cells of a shiftable register. Undesirable range smearing due to relative movement of the target is avoided by aligning each new range sample with the closest of the previously-stored sums. A control signal is generated to represent the estimated relative movement of the target for a particular interpulse period. Alignment is achieved by then shifting the register responsively to the control signal so that the closest stored range sample is summed or integrated with the new, incoming range sample. (Author)
