The phrase "amplitude of the echo" is correct and usable in written English.
It can be used in contexts related to sound, acoustics, or physics when discussing the strength or intensity of an echo.
Example: "The amplitude of the echo was significantly higher in the canyon, creating a dramatic auditory effect."
Alternatives: "strength of the echo" or "intensity of the echo".
The amplitude of the echo is recorded for different spacings of the two pulses.
The first one is fast-time which is included in the complex amplitude of the echo signal and reflects the echo signal varied trend.
Once we have checked the presence of the receiver in, the position of the receiver and the information encoded in are sufficient to determine the delay and the amplitude of the echo associated to that acoustic path.
Thus, the amplitude of the echo at the time t is related to the transverse relaxation T 2, gradient G, self-diffusion coefficient D, gyromagnetic ratio γ, and the half echo spacing τ through the following equation: M_{t} = { exp }left( { - frac{ 1}{{T_{ 2} }} - frac{{gamma^{ 2} G^{ 2} Dtau^{ 2} t}}{ 3}} right) (1).
The large portion of the fastest dipolar decays is completed within the spectrometer dead time tdead (400 ns in our case) and thus is represented only as reduced amplitude of the echo.
The shape and surface characteristics of the environment, such as roughness or absorption coefficient, as well as the distance and the angle of incidence, have high influence on the amplitude of the echoes.
Using this model, and analysing the amplitude of the echoes it is possible to distinguish between walls and corners in a single scan of a single ultrasonic transducer pair.
Various analysis routines specific for Dynasonde applications perform inversions of measured parameters (range, angles of arrival, polarization, line-of-sight Doppler speed, amplitude) of the echoes to retrieve a number of ionospheric parameters (vertical profile of the plasma density, vector velocities of the plasma structures, spectra of small-scale irregularities, etc).
First, the increase of surface roughness resulted in diffuse reflection and consequently decreased the amplitude of the echoes.
A iref is the reference peak-to-peak amplitude of the echoes reflected from the solution-air interface with the same distance as A si.
As a consequence, the amplitude of the received echoes has received little attention from robotic researchers.
