Robust adaptive beamforming for surveillance system using 2D antenna array

摘要

In this paper we propose an algorithm for 2D antenna array that can be used in ground surveillance systems. Due to the multipath propagation of signals robustness against imperfect knowledge about direction of arrival (DOA) is needed. We achieve the needed robustness by using two dimensional Slepian window functions. Although main interest of our research is surveillance, results of it may be also implemented in other domains of CNS (communication, navigation and surveillance). It is so because relatively similar nature of the systems — they all exchange data between avionics and ground based systems.
