Research output: Contribution to journalConference articlepeer-review


The location dependent effect of acoustic field received by a linear array is modeled as an extra `loss' factor in the complex spectral variable. A high-resolution algorithm combining the Singular Value Decomposition Method and the Eigen-Matrix Pencil Method is then employed to find the complex directions representing the incoming directions and the location dependent factors of multipath and multimode arrivals. Five key features (namely, noise immunity, robustness, resolution, accuracy, and physical insight) of the proposed algorithm are studied using numerical examples.
