Source Bearing Estimation In A Coherent And Incoherent Environment Using A Single Eigenvector
Dan Madurasinghe · Information Sciences, Signal Processing and their Applications · 1996
A direction finding technique suitable for coherent and incoherent signal is presented. The method utilises only a single Eigenvector of the array covariance matrix. This is particularly useful when the covarinace matrix is very large. Consider M uncorrelated narrow band sources of This is achieved by introducing a moving data window using magnitudes a, (t ), ( m = 1,2,. . . M), impinging on the a single Eigenvector to construct a set of linear independent
