SC-SSF DOA Estimation with Mutual Coupling Presence

摘要

In this paper basing on the SC-SSF (spectrum correlation signal subspace fitting) eigenvalue decomposition principle, estimating the DOAs of radiation sources using an antenna array with mutual coupling existing among elements is investigated. We analyses the effect on the SC-SSF algorithm for the mutual coupling among the elements. And this paper provides an algorithm to calibrate the effects. The computer simulation results show that this approach is very valid to counteract the mutual coupling.
