Direction finding for an extended target with possibly non-symmetric spatial spectrum [PDF]
, 2004 We consider the problem of estimating the direction of arrival (DOA) of an extended target in radar array processing. Two algorithms are proposed that do not assume that the power azimuthal distribution of the scatterers is symmetric with respect to the ...

Polynomial Manifold Interpolation for Direction Finding in the Presence of Mutual Coupling
IEEE Access, 2019 Direction-of-arrival (DOA) estimation in the presence of mutual coupling among the antennas is an important problem in direction finding systems. To address the mutual coupling issue, a polynomial manifold interpolation approach is proposed in this paper.
