Modified Cumulant-Based DOA-Matrix Method
Quan Liu · Journal of National University of Defense Technology · 2001
A cumulant based direction of arrival(DOA) matrix is proposed, whose eigenvalues and eigenvectors can be used to get the estimates of signal directions. It differs from other doa matrix methods in that it relaxes the requirements for array geometry, makes better use of the array aperture and is based on cumulant, which makes the new algorithm insensitive to Gaussian noise.
