AbstractVoss Scientific proposes an innovative methodology to determine the susceptibility of electronic systems to electromagnetic interference. Termed the Automated Susceptibility Test Architecture (ASTA), this novel adaptive approach will result in decreased test times and potentially discover unique waveforms that will substantially reduce the intensity of the microwave illumination required to cause the desired effect. The architecture includes an agile RF source controlled by an intelligent automation application. By reducing the required intensity, missions scenarios which were previously impractical will be within reach. The potential benefits of this technique include smaller High Power Microwave (HPM) sources, longer stand off ranges, more reliable results, improved hardening methods, and reduced collateral effects on unintended targets. In addition, the autonomous technique proposed will greatly increase the breadth and number of illumination conditions which can be achieved in the time available for testing, and reduce the manpower required to execute the test. This improvement in efficiency is highly beneficial to both commercial EMI and military applications. By leveraging the previous investment by the Air Force in both RF / microwave test equipment and data acquisition software, a demonstration of this concept can be completed within the constraints of Phase I funding. BENEFIT: The capability to explore the RF illumination parameter space with both increased breadth and detail using an automated system will provide enormous benefit to both the military HPM community and the commercial EMI industry. The primary benefit to the military is the capability to perform previously impossible missions. The reduced susceptibility levels obtainable with this technique will allow the use of smaller sources at longer standoff distances. This capability also provides the information needed to improve RF shielding and hardening for US systems, providing an increased level of confidence on the battlefield. In addition, the customized waveform produced by the system is unique to the target asset. This greatly reduces the probability of undesired collateral effects on unintended targets. The commercial EMI industry will also benefit from improved hardening capabilities provided by this approach and by the general test automation methodology. The improved efficiency and reduced manpower required for the test will be an advantage to both military and commercial users.
