UNCLASSIFIED, PUBLIC RELEASE Susceptibility of EO/IR Sensors to High Powered Microwave (HPM) Systems We have evaluated the susceptibility of a variety of EO/IR sensors to electromagnetic interference. The purposes of the effort are both to determine optimal waveform parameters for generating effects against an electrically small target while also informing related efforts to develop protection against relevant electromagnetic interference. For the purpose of examining and demonstrating the method, we have fired waveforms of varied parameters against these EO/IR sensors in a Gigahertz Transverse Electromagnetic (GTEM) cell, optimizing for lowest field strength required to consistently achieve an effect. To limit the scope of the evaluation, we focused on consistently achieving any type or level of observed effect, optimizing waveform parameters towards lowest incident field. Future Work: We intend to build system level, multi-domain models of the target system for comparison to the physical GTEM testing in a related effort to develop a robust simulation capability for quickly, effectively, and efficiently determining optimal lethality of new targets, especially in a period of conflict during which targets rapidly evolve.
