N2 - The authors present compact closed-form formulas for the Cramer-Rao bound corresponding to the joint estimation of the directions-of-arrival, the signal covariance matrix, and the noise variance. Using these formulas the authors investigate the effect of signal correlation on the achievable accuracy of direction finding systems in a correlated signal environment. As expected, estimation accuracy decreases with increasing correlation magnitude. Correlation phase has a strong effect on DOA estimation accuracy under certain conditions (small aperture, high correlation magnitude).
