Abstract EN
In this paper, a direction of arrival (DOA) estimator is proposed to improve the cyber-physical interactions, which is based on the second-order statistics without a priori knowledge of the source number.
The impact of noise will firstly be eliminated.
Then the relationship between the processed covariance matrix and the steering matrix is studied.
By applying the elementary column transformation, an oblique projector will be designed without the source number.
At last, a rooting method will be adopted to estimate the DOAs with the constructed projector.
Simulation results show that the proposed method performs as well as other methods, which requires that the source number must be known.
