Prony方法用指数函数的线性组合来描

述等间距采样数据的数学模型，可以

同时分析出信号的频率、幅值、初相

和衰减因子。-Prony method to trace with a linear combination of the exponential function

Of equally spaced sampling data, the mathematical model of can

At the same time, analysis the signal frequency, amplitude and initial phase

And attenuation factor
