Prior Knowledge-Based Direction of Arrival Estimation
2011 (English)In: 2011 IEEE International Conference on Acoustics, Speech and Signal Processing: (ICASSP), IEEE , 2011, 2540-2543 p.Conference paper (Refereed)
In a number of direction of arrival (DOA) estimation applications there exists prior knowledge about the sources whose bearings are to be determined. We study the case when this prior information concerns some of the source positions and their correlation state, which is a relevant case in, for example, RADAR scenarios where stationary objects exists in the regions of interest. Traditional DOA methods are not designed to exploit such information, and thus cannot obtain the highest theoretical accuracy. We present a method that can utilize in an asymptotically efficient manner both knowledge on some source positions and that the source signals are uncorrelated.
