| 摘 要： | 本文讨论了适用于具有对称双边响应的线性系统的自回归——运动平均(ARMA)模型及其参数估计方法。将这一模型应用于计算机综合的阵列式声波测井全波列纪录数据的频率——波数域分析的结果表明,以相当短(约1.5m)的空域纪录可获得系统频率——波数城传递函数的非常精确的估计。

| Abstract: | Autoregressive-moving Average (ARMA) modeling for a linear systemwith symmetrical two-sided response function and its parametersestimation method are proposed for solving the inverse problem of acylindrically guided acoustic wave. Applying the method to the syntheticmicroseismograms shows that an accurate estimation of the transferfunction in frequency-wavenumber domain can be obtained by making useof an array data which is reasonably short in space domain. |
