Abstract

The eigenstructure approach for array processing is examined for the general case in which it is required to estimate several parameters related to the directional patterns of the sources and the sensors as well as parameters related to the location of the sources. The assumption of the MUSIC algorithm that any given source is observed by all the sensors with the same intensity is removed, and hence, the proposed technique is useful for localizing emitters in the near field of the array and for using sensors with known phase but unknown gain pattern. The resulting method is illustrated by simple examples, which are also used to show that the standard MUSIC algorithm does not work when the assumption of equal intensities is violated.
