摘要
本文从一种不同于二维谱分析的新观点出发,研究二维谐波恢复问题,证明了白噪声中的二维正弦波的线性模型是一个特殊的二维ARMA过程,并提出了一种时域分析法,借助它可以高分辨检测出白噪声中的二维正弦波。
This paper analyzes the two-dimensional (2-D) harmonic retrieval problem from a new viewpoint which is different from 2-D spectral estimation. It is shown that 2-D sinusoids in white noise can be modeled as a special 2-D ARMA process. A time domain analysis method is proposed for resolving several 2-D sinusoids in white noise.
