The technical feasibility of a high performance on-hull elf antenna will be determined by a comprehensive investigation of on-hull elf noise as a basis for determining feasibility of three adaptive concepts: (I) a real-time stochastic adaptive process; (II) a real-time deterministic adaptive system, speed, acceleration and shaft speed; and (III) an array of short highly directive and sensitive fiberoptic sensor elements. An analytical system description of each of the three concepts will be developed based on characteristics of each practical element of the system. First order approximations will be used to characterize system performance. Performance criteria will be developed and applied to a comparative evaluation of the concepts and practical feasibility of the best approach will be assessed.
