Cross Validation Based Distributed Greedy Sparse Recovery for Multiview Through-the-Wall Radar Imaging

Algorithm 2

CV-CSOMP.

Input: Reconstruction vectors , CV measurement vectors , reconstruction matrices , CV matrices , the

number of iterations , and the censoring level .

Initialization: Set the CV residual , ;

Iteration: (1) Reconstruct using the CSOMP algorithm with , , and ;

(2) Update the CV residual , ;

(3) Until , compute the measurement noise level ;

Output: The sparse solution .
