Intraweapon Wireless Communication

"A novel method of intraweapon communications using magnetic field transmissions along with new very low power Spin Dependent Tunneling (SDT) magnetic sensor receivers will be developed underthis program. Normal physical wire communication links cannot be expected to survive during and after target penetration. Therefore, wireless methods of communications must be developed. THE PROMISING methods of communication within the munitions willbe studied and evaluated. This includes RF, magnetic and any other method that can be determined feasible during this study. A new technique called Magnet Induction holds promise for small, confined areas in metal canisters ANDPENETRATOR BOMB BODIES. NVE Corporation will team with Alliant Techsystems (ATK) as a subcontractor to combine their knowledge in munitions and fuzing systems with NVE's expertise in magnetic sensors, wireless networks (LAN) and high shock recorders todesign, model and construct a breadboard model of the most promising technology. Magnet Induction technology will be closely investigated since it is effective over distances up to 3 meters, is low power, uses very small antenna coils/magnetic sensors andcan be commercialized for the Personal Area Network (PAN). Both the Military and commercial industry will benefit from this product by being able to comunicate inside munitions during and after impact. Synchronized measurements of events will allowdistributed control not pos
