As shown by the comparison with original MSA  it appears that this new technique solves the problem that MSA algorithm is sensitive to illumination and the computational load is significantly reduced to 1/8th of that of the original MSA algorithm  it is also robust to affine transform  light projective transform  noise  thin fog  occlusion and illumination change. the performed experiments show that it has fast searching speed  and can accurately recognize and locate target in real scenes. 2012 IEEE.   Fast-forward solvers for the low-frequency detection of buried dielectric objects 期刊论文  OAI收割 Ieee Transactions on Geoscience and Remote Sensing, 2003, 卷号: 41, 期号: 9, 页码: 2026-2036 作者:  Zhang YH(张云华) 收藏  |  浏览/下载：30/0  |  提交时间：2014/05/04 buried objects  conjugate-gradient fast Fourier transform (CG-FFT)  algorithm  cyclic convolution  cyclic correlation  fast extended Born  approximation  half space  low-frequency numerical simulation  extended born approximation  ground-penetrating radar  electromagnetic  scattering  3-dimensional bodies  fft method  simulation  inversion  transform  algorithm  size
