Abstract

This paper presents a direct multi-target localization algorithm for multiple-input multiple-output radar networks employing code division multiple access signals. The proposed algorithm localizes targets one by one whose contributions remain dominant in the received signal after removing the contributions of the localized targets. The sequence of isolating the contributions improves the accuracy of multi-target localization and avoids the computational inefficiency of the maximum likelihood estimator (MLE). Simulation results demonstrate the superiority of the proposed algorithm in comparison with the MLE.
