Abstract: arrays are fundamental to localization applications. Specifically spares arrays can provide superior direction-of-arrival (DoA) estimation performance with limited number of sensors. There has been increased interest in the research community in designing 2D sparse arrays with performance improvement and complexity reduction. The research efforts are uncoordinated resulting in some repetitions and sometimes conflicting claims. After introducing 2D sparse arrays and their importance, this paper establishes the … Show more

“…These arrays are optimized on the basis of open box arrays (OBAs) to reduce the mutual coupling. In addition, thermos arrays [14] and sparse active rectangular arrays [15] also belong to this kind of array, which is usually called special 2D sparse arrays [16]. This kind of array uses covariance symmetry and geometry symmetry to achieve sensor separation.…”
