Abstract
MZA proposes refinement and optimization of a novel method of atmospheric phasing for a distributed array of sub-apertures enabling high-resolution imaging. The phasing method derives tilt correction through sub-aperture image shifts used to approximate sub-aperture piston correction with linear estimation. Piston correction is optimized through image-metric-based feedback, resulting in an accurately phased high-resolution image through the array. The applied phase modulation affects the receiver optical train as well as any outgoing common-path lasers. To digitally demonstrate the performance of phasing concept, MZA will refine a WaveTrain wave-optics simulation incorporating the sub-aperture phasing system as well as a transmitter phasing system for outgoing lasers. The wave-optics model will incorporate target models, atmospheric turbulence, and may include aero-optics disturbances for an aircraft platform. MZA has teamed with Battelle Memorial Institute (non-profit) making use of Battelle’s investment in graphics processor unit (GPU) technology for rapid parallel image processing. A laboratory demonstration of MZA’s phasing concept will be conducted during Phase I, including GPU-implemented processing of sub-aperture and high-resolution images. Optical and computational hardware will be evaluated during Phase I to support a preliminary design for a meaningful test of the sub-aperture phasing and imaging system during Phase II.
