摘要：
The rotation of an antenna array will degrade the accuracy and precision of superresolution algorithms used to estimate the directions of arrival of the signals present. The degradation is caused by the apparent motion of the signals during the period that the spatial covariance matrix is being estimated. In this paper a new method which compensates for the apparent motion is presented. The technique succeeds in reducing both the bias and variance of the direction finding results. Performance examples are shown for the popular root-MUSIC algorithm.
