Abstract The problem of estimating the Direction-Of-Arrival(DOA) of multiple source sig-nals far from the sensors using a novel adaptive antenna suggested by Du Huiping(1999) in the presence of spatially white Gaussian noise is addressed based on the Maximum Likelihood(ML) function approach. The effects of the Signal to Noise Ratio(SNR), snapshots and space of sen-sors are investigated. The statistical performance of ML estimators as well as the Cramer-Rao Bound(CRB) are analyzed. Comparison of the simulation results with the other articles shows the validity of the theoretical analysis.
