Abstract :
In this paper, the problem of nonlinear phase coupling estimation of two-dimensional harmonics is discussed, which has not been solved before. From the definition of third-order cumulant of the data, we separate the coupling harmonics and the other harmonics. Then, we select one method of two-dimensional harmonics retrieval to estimate the parameters. Both the complex and the real signal are concerned
