Adaptive Circumvention and Recovery Architecture for Radiation Effects Survivability

Electronics in ICBMs and other guided ordnance delivery vehicles are held to high design standards for performance and reliability. Adding complexity to their design, it is necessary to implement components and circuits to withstand highly energetic particle events associated with nuclear detonation. Creare proposes a concept to employ a rapid circumvention and recovery (C&R) strategy to enable electronics and critical data survival during such an event while requiring limited radiation hardening. Innovative firmware optimizes process timing and sequencing during C&R to ensure hardware survival and decrease latencies associated with GPS signal reacquisition. The objective of Phase I will be to establish a nominal architecture to demonstrate operational features of the C&R architecture. This architecture includes hardware interconnection and firmware development culminating in a total system assessment of immunity to a specified total ionization dose and related single event effects of onset gamma particles. During Phase II the architecture will evolve to endure upsets designed to affect electrical performance and perturbations in data where enhanced protection circuitry, component/data redundancy, and error detection/correction will be refined to counter these adversities. A detailed modular simulation of the entire system will be executed to verify performance prior to actual RH testing.
