Abstract

A four-quadrant frame of reference, established with respect to a sensed target image, effectively converts the image into a composite target regardable as the union of four, quadrant-based target-segments. Four subgates, each established within a different reference-frame quadrant, become in union a composite tracking gate. As the effectualization of the actual gate-sizing, the degree of conformity between the composite gate and the composite target is then optimized by optimizing the degree of conformity between the subgates and the associated target-segments.
