1. A method for correlating data from a slow scan sensor with a target for maintaining tracking of the target during target maneuvering, comprising: providing a maneuver gate to monitor a predetermined volume disposed about a velocity vector of the target, the velocity vector available from a historical track of the target, wherein the volume is bounded by inner and outer intersecting ellipsoids; examining the data for a potential detection when target correlation has been disturbed; and correlating the target with the detection when the detection lies within the volume.
