In order to demonstrate lock-on-after-launch (LOAL) capability, imaging infrared missile systems of the future require the ability to autonomously identify and track targets of interest. A robust algorithm architecture must have the flexibility to accommodate the fluid system requirements that drive its design. This paper describes a method to autonomously acquire and track an extended range target through its entire flight scenario. A proven automatic target recognition (ATR) approach is used to detect and identify targets of interest, separating them into non-targets and clutter. The methodology uses a down selection strategy to nominate targets for terminal track. Once nominated, a Weighted Edge Tracker (WET) is employed. The tracker relies upon correlations of appropriately weighted edge directions from frame-to-frame images and reference templates. This combination of automatic target recognition and terminal tracking provides a sophisticated yet simple approach to many challenging long range tracking problems.
