We propose development of an efficient physics-based computational capability for real-time radar location of targets in cluttered environments. Our effort will focus, in particular, on air traffic targets in static natural environments that include dynamic effects such as spinning wind turbines. The proposed methodology models radar signal scattering in cluttered environments on the basis of the time-dependent Maxwell's equations formulated, in a single computational methodology, in terms of 1) Moving- and fixed-domain overlapping computational meshes, as well as 2) The dispersionless Fourier-Continuation method, and 3) A novel methodology for evaluation of computational boundary conditions and long-range propagation at essentially zero cost.
Benefit: Our effort seeks to provide a software solution for users of simulation tools for which the limitations implicit in existing solvers represent a significant handicap. These include the military, (Navy, Air Force, and Army) as well as commercial concerns (air-framers, space research agencies, remote sensing and medical imaging developers, etc). Thus, there is a significant market for the proposed improved innovative solutions in high-tech industry, and in pursuing the present project MathSys Inc. seeks to cater to that need. Our connections with DoD and industrial scientists, as described below, form the basis of our overall commercialization strategy.
