Résumé:
These last three decades, many second order (SO)
and higher order (HO) high resolution (HR) direction finding
(DF) methods, such as 2q-MUSIC (q ¸ 1), exploiting the
information contained in the SO or HO circular (C) cumulants
of the data, have been developed. However, for 2qth-order noncircular
(NC) sources such as M-PSK sources with M · 2q,
strong gains in performance may be obtained by taking into
account the information contained in both 2qth-order C and NC
cumulants of the data, giving rise to NC 2qth-order DF methods.
Numerous NC DF methods have been developed these last fifteen
years but mainly at the SO and under restrictive assumptions
on the sources. The purpose of this paper is to give new insights
into NC 2q-MUSIC methods for 1 · q · 2 and for arbitrary NC
sources
