Paper Abstract

Superoscillation is a novel super-resolution method based on the propagation wave instead of evanescent waves and its limitation is increasing resolution with huge sidelobes. We developed a super-oscillation function filter based on Chebyshev linear array, which overcame the diffraction limit with lower side lobes in 4F system. It was proved that value of MSE and PSNR of single point and multipoint samples imaging reduced a half.
