A Novel High-resolution Algorithm for DOA

In the paper was proposed a novel high-resolution algorithm,fast projection matrix algorithm(FPMA) as the number of the signals M was known prior.FPMA formed the projection matrix Vq to estimate DOA of the signals by the covariance matrix R.The computation load of FPMA was O(N2M),which was less than those of other high-resolution algorithms.It's proved that FPMA could perform well in DOA estimate.Computer simulations testified that FPMA did better than Capon and as well as MUSIC on the same condition when q is not less than 2.
