摘　　要：本文提出了一种基于Tucker分解的频率和时延联合估计算法。通过相邻阵元接收的正弦信号之间的时延特征构造信号张量,其频率和时延信息可利用张量Tucker分解之后的信号子空间通过ESPRIT算法求得。计算机仿真验证了所提算法的性能。In this paper, we develop an algorithm based on tucker decomposition method for estimating the differential delay of a sinusoid signal received at two separated sensors as well as the sinusoidal frequencies. Using tucker method, the reconstructed signal tensor is decomposed, the frequency and time delay estimates are obtained by ESPRIT from the signal subspace. Performance evaluation via computer simulations is included to demonstrate the effectiveness of the proposed algorithm.
