Pseudo-Trapezoidal Fast Factorized Backprojection Algorithm for Near-Field Sparse MIMO Array 3-D Imaging

Abstract: In the near-field condition, the wavenumber spectrum exhibits spatial variance, which renders the fast factorized backprojection algorithm (FFBPA) ineffective in improving the imaging ...
