Abstract
A tracking antenna system includes coarse (CEA), medium (MEA) and fine (FEA) antenna arrays symmetrically disposed with respect to a boresight (BST) and controllably connectable to signal processing units (SPU) such that the antenna platform (PTF) is moved to point the boresight in the direction of a target while progressively increasing the resolution of the angular difference between the boresight and target. There are provisions for backtracking to decrease the resolution if the angular difference goes out of selected ranges.
