Thinned Array Imaging Experimental Study in Anechoic Chamber

The anechoic chamber experiment is carried out to prove that in practical condition the thinned array aperture synthesis method can avoid the thinned array high sidelob, and the imaging algorithm based on compressed sensing theory can reconstruct the sparse target. For the array errors in experiment, the corresponding calibration methods are presented. Via experiment data processing, the validity of array error calibration method, the thinned array aperture synthesis method and the imaging algorithm based on compressed sensing theory are testified.
