本文在研究了二维谐波信号相关矩阵后,提出了一种称之为“矩阵束的二维谐波恢复(MP2D)”算法,该算法既不需要求解二维特征多项式的根,也不需要在二维频率空间搜索谱峰,算法具有高效性。仿真实验表明,该算法在白噪声条件下对二维谐波频率估计具有高的精度和强的抗干扰能力。
After studying the correlation matrix of two-dimensional harmonic signal, this paper proposes a two-dimensional harmonic recovery (MP2D) algorithm called “matrix beam”, which neither need to solve the root of two-dimensional characteristic polynomial nor The spectral peaks need to be searched in two-dimensional frequency space, and the algorithm has high efficiency. Simulation results show that the proposed algorithm has high accuracy and strong anti-jamming ability for two-dimensional harmonic frequency estimation under white noise conditions.
