  • Abstract
    This letter describes efficient synthetic aperture radar raw data generation in the wavenumber domain using inverse processing. An exact form based on an inverse Omega-k algorithm and an approximate form based on an inverse Chirp Scaling algorithm are described, and examples are presented for a point scatterer. A methodology to incorporate the anisotropic behavior of an urban scene in a reflectivity map is also presented and demonstrated by means of a subaperture analysis.
