摘　　要：针对色噪声背景下的二维谐波频率估计问题 ,本文提出了拓广的二维ESPRIT算法 .该算法对二维MA模型的噪声具有比较好的抑制能力 .同时 ,对于二维频率配对问题 ,本文给出了一种更为简便的方法 .An extended ESPRIT type method was presented to extract frequencies from the signal which was contaminated by two-dimensional colored Gaussian noise. If the noise has the characteristic of MA model, this method can restrain it effectively. In addition, a new pairing method was also presented. Theory and algorithm are illustrated by simulation examples.
