Abstract
Phased array antennas are widely used in many applications and consist of many antennas coupled together to enable digital beam-forming. As transmit/receive elements begin to degrade and eventually fail the antenna’s beam will distort from the desired pattern. We propose a novel optimization algorithm which takes into account not only the current state-of-health of the system, but potential future states-of- health from prognostic observations. The approach can be run entirely off-line (before the start of a mission), so requires no additional computational resources or sensors be added to the system and does not require the system to be able to detect the degradation/failures during a mission. Our main objective is to trade some current optimization flexibility for improved system robustness under future failures.
