AbstractTanner Research proposes to implement a fast-response optical proximity fuze for use with active protection system (APS) counter-munitions (C-M). Use of fast back-end sensor processing inherent in optical systems that implement optical-flow and looming algorithms will be critical in achieving the warhead response times needed to defeat incoming 4000 fps threats: and, especially incoming threats passing off-center to the C-M axis. A single optical sensor can simultaneously detect the threat and determine into which specific radial zone the threat will pass the C-M warhead in a near-miss scenario. Knowing which 30A radial (i.e., 12 in 360A ) will facilitate focusing about 90% of the warhead blast and fragmentation from a directional warhead into any 90A sector. Algorithms for fuze command formulation based on looming detection will be evaluated and refined. Finally, options for low-cost, monolithic, micro-size implementations will be considered to establish a roadmap for a prototype system in Phase II.
