New method of constructing the projection matrix for array processing in single snapshot case

Abstract

In the paper, a new method of constructing the projection matrix for array processing, using a uniform linear array in the single snapshot case, is presented. The method is computationally simple, independent of the coherence of signal sources and beneficial to real-time processing. Good performance can be obtained when the signal-to-noise ratio (SNR) is high. Simulation results show the effectiveness of the new method.
