Abstract :
In this paper, a new algorithm is presented for signal selective direction of arrival (DOA) tracking of multiple moving sources emitting narrowband or wideband cyclostationary signals. The most current array outputs are used to update the DOAs recursively and no data association is needed in this algorithm. Furthermore, by exploiting cyclostationarity, interference and noise are suppressed. Thus only sources of interest are tracked. The effectiveness of this new algorithm is demonstrated by simulations
