摘要：
This correspondence considers the problem of direction-of-arrival estimation using sensor arrays composed of two identical, uncalibrated, and rotated subarrays. It is shown that such arrays do not provide an identifiable parameterization of the problem; i.e., unlike ESPRIT, unique estimates are not possible when more than one signal is present.
