本文的新奇是提出了一种有效的方法，用于检测和定位的布线故障的传递函数分析，使用时域反射法（TDR）的方法，迭代反卷积和优化技术。本文展示了如何使用迭代反褶积和优化技术来定位硬故障，小的不连续性和提高信噪比。所开发的方法也可用于表征网络的分支中的导线故障。应用自适应滤波器来降低反卷积噪声。应用短窗函数、最优补偿和自动正则化技术这三种频域反褶积技术求解了入射波和反射波之间传递函数的不适定反问题。将该方法应用于屏蔽同轴电缆和双绞线电缆的故障定位。
The novelty of this paper is to propose an efficient method for the detection and location of wiring faults with transfer function analysis using time domain reflectometry (TDR) method, iterative deconvolution and optimization techniques. The paper shows how iterative deconvolution and optimization techniques are used to locate hard faults, small discontinuities and enhance the signal-to-noise ratio. The developed method can also be used to characterize the wire faults in the branches of the network. The adaptive filters are applied to reduce the deconvolution noise. The performance of three frequency domain deconvolution techniques, the short window function, the optimum compensation and the automated-regularization technique are applied to solve the ill-posed inverse problem for the transfer function between incident and reflected waves. The proposed approach was applied to locate faults on the shielded coaxial cables and twisted pair cables.
