Abstract

In the presence of circular complex-valued multiplicative and additive noise

we proposed a crosscorrelation estimator for the 2-D direction of arrivals of narrowband source impinging on a uniform circular arrays (UCAs).Further

we analyzed the statistics performance of the estimator and gave the selection criterion of the optimal parameters.This estimator can efficiently eliminate the multiplicative and additive noise in the source and retain the better performance of the UCAs.It is provided with less computational load.Numerical simulations validated the theoretical results.
