Therefore, the most commonly used technologies for measuring the position of an object involve sending energy towards the object to be measured, collecting the echo signal, and analyzing this echo signal to determine the position of one or several objects located in the sensor's field of view.
The fault distance is measured, the defects of the optical time domain reflection technology is overcome and fault detection in high spatial resolution achieved that is independent of distance measurement can be achieved by the cross-correlation operation of the reference signal and probe light echo signal [3].
For generation of figure 5 model uniform white noise is added to the original voice signal, Echo signal in figure 6 model is generated by using delay element and then adds it with voice signal and in last model, echo signal and uniform white noise is added with original voice signal.
i] is readily performed for simple wavelength spectral functions, allowing analytical approximations for the "resolution" echo signal to be obtained in the absence of depolarizations resulting from instrumental imperfections.
They cover statistics of CDL echo signal, statistics of lidar estimates of the radial velocity and Doppler spectrum width, measuring wind velocity and direction, estimating atmospheric turbulence parameters from wind measurements, and lidar investigations of aircraft wake vortices.
Abstract: Experimental control system for caterpillar mobile robot featuring ultrasonic sensors with analog echo signal processing is described.
The essence of the dynamic focusing of the acoustic array beam which receives information is that the overall array echo signal is accepted from the ultrasonic beam focus area by shifting accordingly real time delay of echo signals in the separate piezo element arrays.
For a strip of 50 units long on the vertical axis, the duration of the corresponding echo signal is: 50 X 4 ns = 200 ns.
Adaptive Control monitors the process forces of the machining tool, while the Acoustic Control registers the intensity of the tool vibration on the workpiece surface via an electrical echo signal, as well as the status of the coolant pressure.
There, this signal is recorded as a so-called echo signal by the second EMAT receiver.
The second pulse increases the amplitude of the oil signal and an echo signal is obtained.
