Abstract

We propose a modification in the MODEX method for direction finding using array of sensors. This proposal alters the MODEX candidates for the estimation and, as a consequence, reduces the computational effort, improves the performance and preserves the optimum asymptotic efficiency for both uncorrelated and correlated (coherent) sources.
