Abstract
The deterministic and stochastic direction estimation Cramer-Rao bounds (CR Bs) are studied in the presence of one signal and spatially uncorrelated se nsor noise with unknown nonequal variances in array sensors. The explicit C RB expressions are obtained, and their relationship is studied showing some typical properties inherent in the nonidentical noise case.
