Course Description

Study in-depth signal processing options for synthetic aperture radar image formation. Focus on Fourier domain inversion methods of Polar Formatting and the approximation-free signal processing technique variously called the Omega-K, Range-Migration or Wavenumber Interpolation algorithm. Examine in mathematical detail Polar Formatting and Omega-K algorithms. Explore recent advances in computationally efficient (factorized) Back-Projection algorithms and relationships between SAR, Fourier optics, and inverse diffraction theory.
