A Novel Sparse Array Configuration with Low Coarray Redundancy for DOA Estimation in Mobile Wireless Sensor Network

Abstract: For tacking and localizing sources in the mobile wireless sensor network, underdetermined direction of arrival (DOA) estimation with high-accuracy is a crucial issue. In this paper, a novel sparse array configuration is developed for accurate DOA estimation from the perspective of sum-difference coarray (SDCA). As compared with most of the existing sparse array configurations, the proposed array can effectively reduce the overlap between difference coarray (DCA) and sum coarray (SCA) and can achieve more conse… Show more

“…WSN is composed of a large number of low-power, microsmart sensor nodes that are randomly deployed to perform sensing tasks in the monitoring area. In recent years, WSNs have played an important role in the production of life, environmental monitoring, national security, and other fields [1][2][3][4][5]. Because sensor nodes are usually powered passively with limited energy and weak computing power, it is important to build an energy-efficient WSN.…”
