Alternating between reflection in that way corresponds to the bits in the transmitted data: For a reflected wave
, the receiver decodes a 1; for no reflected wave
, the receiver decodes a 0.
If the source impedance is also not matched to the line, this reflected wave
will continue to travel back and forth between source and load, getting partially absorbed each time, until all its energy is depleted.
The direction of and the distance to an airplane are detected by emitting radiation from the ground and receiving the reflected wave
from an airplane.
When this interacted with the entrance of the delamination, there was a low amplitude reflected wave
In Figures 11-14, [S.sub.d] refers to the direct wave signal and [S.sub.r] is the reflected wave
signal from the rebar-concrete interface.
When the incident wave illuminates the chessboard-like plane normally, the reflected wave
will be the superposition of the reflected waves
from region I and region II.
Then, the data processing method was adopted to obtain the incident wave and reflected wave
at the nominal contact surface S'.
In this case, the wave pattern after the cumulation of the reflected wave
at the symmetry axis is the most complicated since the wave interacts with the set of transverse waves which were formed in the conic expansion part (see Figures 3(d) and 3(e)).
The arrival time and amplitude of the reflected wave
vary with the location and the dielectric discontinuities of material (e.g., air/bark and bark/ anomaly) .
Since they feature flat surfaces, the reflected wave
is not diffusive enough to reduce the sound on the road.
It is also noticed that the more energy is transferred by the reflected wave
of surface mode than the reflected wave
of interface mode.
The advanced detection by using reflected wave
method is started early in the field of traffic tunnel.
