Projection approach to bearing estimations
Chien-Chung Yeh · IEEE Transactions on Acoustics Speech and Signal Processing · 1986
Bearing estimations based on the projection approach are discussed. A method is presented which computes a projection matrix by using any M rows of the covariance matrix, where M is the number of radiation sources. This method requires considerably fewer computations than projection techniques using eigenvectors, especially when the number of array elements is much larger than the number of sources. Simulation results are presented also.
