摘要
Abstract
For the robustness problem of direction finding algorithm using uniform planar arrays under mu-tual coupling,a rank reduction based self-calibration algorithm is proposed. Based on the priori knowledge of mutual coupling,the perturbed array response is just rearranged in the transform domain,thus being able to mask the adverse effect of mutual coupling,and avoid the aperture loss as well. Then according to the rank reduction criteria,the reduced-dimension processing is performed by applying suitably designed esti-mation procedure. Moreover,an accurate estimation of coupling coefficients can also be acquired for array calibration by eigen decomposition. Compared with the existing method,the proposed algorithm is more nu-merically efficient with improved accuracy.关键词
