Abstract :
Interpolation-free Stolt mapping, based on Fourier transform and phase multiplications, is proposed. Benefiting from this method, an efficient wavenumber domain algorithm (E-ω-k) can be achieved for generic synthetic aperture radar imaging. The method is finally demonstrated using simulated data.
