Abstract

In this paper, a new signal-selective direction-of-arrival (DOA) tracking algorithm is presented for moving sources emitting narrowband or wideband cyclostationary signals. In this algorithm, DOAs of the sources are updated recursively based on the most current array output in a way that no data association is needed. Furthermore, by exploiting cyclostationarity, interference and noise are suppressed. Thus, only sources of interest are tracked. It is also shown that via a Kalman filter, tracking performance of this algorithm could be further improved. The effectiveness of the proposed algorithm is demonstrated by simulations
