Parameter method was adopted to generate time series conforming to the specified power spectrum . a autoregressive model was estimated by program which based upon yule - walker equation . good agreement was obtained between the simulated spectrum and the target spectrum 本文利用ar参数模型方法根据阵风功率谱模拟产生相应的风速时间序列，编写了相应的matlab模拟程序，并计算得到了ar模型的参数，结果表明模拟信号的功率谱与原始谱比较一致。
