摘要 本文研究了一般阵列误差情况下的空时二维鲁棒参数估计方法 .首先本文给出了一般阵列误差模型 ,然后基于该模型提出了空时加权子空间拟合 (ST WSF)算法 ,并给出了信号参数 ,即信号波达方向和频率的估计的Cram啨r Rao下界 . The robust spatio-temporal signal parameter estimation is studied in this paper in the case of general errors. First a general array error model is given. Then a spatio-temporal weighted subspace fitting (ST-WSF) method is proposed on the basis of the given model. And the Crame´r-Rao lower bounds on signal parameters, i.e. directions of arrival and carrier frequencies, are derived. Numerical experiemtns further verifies the effectivments of the algorithm.
