“…Detection and direction-of-arrival (DOA) estimation using an array of sensors are important topics in signal processing and have many applications, such as in radar, sonar, communications and acoustics [ 1 , 2 , 3 , 4 , 5 , 6 , 7 ]. Considering moving sources in a noisy environment [ 1 , 2 ], it is desirable to use both the spatial and temporal information for better performance, since the DOAs between consecutive time steps are highly correlated. In [ 7 , 8 , 9 , 10 ], recursive Bayesian approaches are proposed for tracking the DOA of moving sources.…”
