A Technique of Signal Processing for Interferometric Estimation of the Amount of Deposit in Pipes
Source abstract
Abstract
A technique for processing interferometric signals intended for estimation of the amount of deposit in pipes is proposed, which is based on a 2D Fourier transform of the signals considered as functions of two variables (frequency and time). The proposed processing technique is shown to enable determination of the rate with which peaks of signal images diminish. This rate, being a measure of wave absorption in pipe walls, is a reliable characteristic of the deposit amount in a pipe. Application of this technique reduces the time needed for measurements.
