Résumé:
Recently, the 2q-MUSIC (q ³ 2) direction finding algorithm
has been developed for non-Gaussian sources and square
arrangements of the 2qth-order data statistics, to overcome
the main limitations of MUSIC and to improve the
performance of 4-MUSIC for multiple sources. To further
improve the performance of the 2q-MUSIC algorithm, the
purpose of this paper is to extend the latter to rectangular
arrangements of the data statistics, giving rise to rectangular
2q-MUSIC algorithms. It is shown in particular that
rectangular arrangements of the higher order (HO) data
statistics allow to optimize the compromise between
performance and maximal number of sources to be
processed. Besides, it also allows a complexity reduction for
a given level of performance. These results, completely new,
should open new perspectives in HO array processing
