To extract the direction of arrival of multiple sensors from analysis data by a sensor array is a multiple parameter estimation problem. Some important algorithms for spatial temporal processing have been developed in the past decades. A new direction of arrival estimation method using effects of model errors and sensitivity analysis is proposed. Two subspace are used to form a signal space whose phase shift between the reference signal and its effects of model error signal. Since a desired signal is obtained after interference rejection through correction effects of model error, the effect of channel interference on the estimation is significantly reduced. The proposed method in the number of signal sources detectable is not bounded by the number of antenna elements used. Through simulation, we show that the proposed method offers significantly improved estimation resolution and accuracy relative to existing method.
