Abstract

PURPOSE: To make possible the measurement of propagation time by sampling noise of a fixed section from reflection waves composed of noise and reflection pulses, delaying the noise for a fixed time to take its correlation with the reflection pulses and accurately knowing the rise time of the reflection pulses.
