且节省运算量。计算机模拟实验验证了上述结论。
A new approach for estimating two-dimensional (2-D) sinusoidal parameters is presented. The algorithm is based on the singular value decomposition (SVD) of the signal matrix that is formed by the signal eigenvectors of autocorrelation matrix. The 2-D frequencies of sinusoids can be separately estimated in each dimension. In a large number of empirically based examples
this method has been found typically to provide excellent performances with the distinct advantage of low computational requirement and low signal to noise ratio threshold.
