GPU-Based Computational Platform for Performance Evaluation Of HEL Directed Energy Technology

Optonicus proposes development of user-friendly GPU-enhanced computational platform for numerical analysis and performance assessment of wide range of high-energy laser (HEL) beam projection systems. The wave-optics-based software platform will enable high-accuracy predictive performance analysis of different configurations of unobscured, centrally obscured, spatially distributed with multiple subapertures, and/or conformal phased array systems. The proposed simulation platform will take into account critical/key system engineering design constraints (e.g., diffraction, jitter, aero-optic disturbances, atmospheric propagation, thermal blooming, adaptive optics control, coherent/incoherent beam combining, etc.). Additionally, an approach for integration of the proposed software with capabilities for computation of physically realizable vertical profiles of meteorological data will be developed. This feature will enable more precise performance evaluation of HEL beam directors for various geographical locations worldwide. The proposed development builds upon the extensive research and development background of the Optonicus team. It includes unique computational techniques for analysis of wave propagation in both turbulent and refractive atmosphere. It also leverages the companys recent successful transitioning of the developed computational tools to GPU-based platforms (NVIDIAs CUDA) and experience in development of atmospheric sensing, adaptive optics, and fiber array technologies.
