Abstract :
A direction of arrival (DOA) estimation method based on the spectral Capon rooting algorithm is developed. The developed method realises DOA estimation by real polynomial rooting technique rather than a grid search. It provides a lower computation complexity and a better performance compared to the spectral Capon searching algorithm. Simulation results demonstrate the effectiveness of the method.
