“…As recalled in [1], the computational complexity of Geometrical Optics to compute monostatic SCS is O(BN 2 ) with N = (kR) 2 the usual large parameter and B the maximum number of bounces along ray paths.…”

“…Frame based Gaussian Beam Shooting (GBS) has been recently proposed as an alternative to Physical Optics (PO) based techniques (including Iterative PO and Multilevel PO) and ray-based methods (e.g. Shooting and Bouncing Rays) for monostatic scattering computations [1]. The proposed algorithm takes advantage of the Gaussian beam (GB) limited spectral and transverse spatial extents, which lead to dramatic limitation of the number of beams involved in monostatic RCS computations.…”

A Gaussian beam shooting algorithm based on Gabor frame decomposition is proposed for fast monostatic scattering computations in large multipath environments. Formulation and specific features of the method are outlined. Complexity and accuracy of the algorithm are discussed and illustrated by numerical results. A validation strategy based on 2D-to-3D conversion is explored, due to the large electrical size of the problems to be solved with this method.
