Digital Image Generator for Real-Time Display of Nuclear Backgrounds for Optical/Infrared Sensors

High level protection of DOD high power systems against electromagnetic threats that include high intensity radiated fields (HIRF), electromagnetic interference (EMI), electromagnetic pulse (EMP), electromagnetic compatibility (EMC), and electrostaticdischarges (ESD) is highly desired to improve equipment reliability and personnel safety. The option of using conventional shielding materials for electromagnetic radiation hardening tends to exhibit several limitations such as limited frequency rangeof application, excessive weight, high cost, or low flexibility. Sigma Technologies proposes a novel highly effective approach for improving substantially radiation hardening of DOD aerospace systems. The concept consists in the development of aceramic/metal nanophase multilayer composite which will be effective over a wide range of frequencies. In Phase I of this program, Sigma will establish proof-of-concept that the proposed composite will provide improved immunity to electromagnetic effects.In the Phase II work, the process will be transferred to larger scale equipment that is already in place at Sigma to produce large quantities for field tests.The proposed material composite is expected to have superior electromagnetic shielding propertieswhich can be readily transferred to the civilian sector. Applications may include shielding from hazardous electromagnetic radiation of sensitive equipment found in commercial aerospace vehicles, government buildings, hospitals, homes, and schools
