多网格求解泊松方程，给出并解释了一个如何使用多网格求解的过程(I give a short explanation of how to use multigrid to solve the Poisson equation in cylindrical coordinates for a solid conducting pipe. I also explain how to use a non-uniform grid to optimize the problem. )

Many synthetic aperture radar (SAR) image formation algorithms require the computation of a multidimensional Fourier transform of irregularly-sampled or unequally-spaced data samples. We apply a recently developed algorithm, the unequally-spaced FFT (USFFT),2 to SAR image formation and compare its accuracy and complexity to a conventional algorithm. We find that the USFFT algorithm allows comparable accuracy to traditional approaches at a slightly reduced computational cost. We briefly discuss extensions of the USFFT algorithm to multiresolution SAR imaging
