| 摘 要： | 从理论上定量分析了未预期模型误差影响下秩减估计器的方位估计性能。通过对秩减估计空域谱进行一阶Taylor级数展开得到方位估计偏差的表达式,基于此分别推导了秩减估计器的方位估计均方误差和测向成功概率。针对一种用于均匀阵列互耦自校正的秩减估计器给出数值实验,实验结果验证了理论推导的有效性。

| Abstract: | A performance analysis of the RARE was presented in presence of unexpected modeling errors.First,the closed-form expression of direction-finding(DF) error was given through the first-order Taylor series expansion of the spatial spectrum function,and then the mean square error(MSE) and DF success probability of the RARE were derived.The numerical experiments,which were associated with the RARE of mutual coupling self-calibration for uniform array,were conducted to validate the theoretical analysis. |

| Keywords: | rank reduction estimation modeling errors mutual coupling mean square error success probability quad-ratic forms of Gauss vector |
