In this paper, a modified version of the wavenumber domain algorithm (MWDA) is analytically presented and formulated. It is capable of processing the spotlight-mode SAR data. MWDA combines the high accurate focusing of the wavenumber domain algorithm (which is also called range migration algorithm) and the interpolation-free requirement. To avoid costly interpolation manipulation, the inverse scaled Fourier transform (ISFT) is substituted for Stolt mapping. The subaperture processing is used to… CONTINUE READING
