管道监测在许多工业过程和人类活动中起着关键作用，特别是在水资源管理方面。用于泄漏检测的频谱分析响应通常基于快速傅里叶变换（FFT）。本文的目的是开发一种基于滤波对角化方法（FDM）的替代方法，以克服FFT方法的局限性，该方法主要用于核磁共振。由于其健壮性，FDM允许由之字形管道产生的困难。埋地水管一般由存在噪声的边界条件来解决。此外，通过减少窄管道的FFT恢复误差，实现了另一个目标。已经建造了一个实验设施来展示这种替代方法的结果。(C) 2008 Elsevier Ltd版权所有。
Pipeline monitoring plays a key role in many industrial processes and human activities, in particular, for the management of water resources. Spectral analysis response, used for leak detection, is generally based on fast Fourier transform (FFT). The aim of this paper is to develop an alternative method based on filter diagonalization method (FDM), mainly used in nuclear magnetic resonance, in order to overcome limitations of FFT approach. Thanks to its robustness, FDM allows difficulties created by zigzag pipeline. buried water tubes and in general by the presence of noisily boundary conditions to be solved. Moreover, another objective is reached by reducing FFT recovery error for narrow pipelines. An experimental facility has been constructed to show the results of this alternative approach.
