Abstract
A high resolution algorithm for resolving closely spaced incident plane waves impinging on a linear array is presented. Unlike many existing "noise eigenvector" based methods, this "signal eigenvector" algorithm is not susceptible to the difficulties arising from coherent signal sources. A complete theoretical development of this algorithm is provided. Its improved performance relative to the spacial smoothed version of MUSIC is illustrated by simulated examples.
