On this reflected component, a strong fading effect is visible, but as described earlier, this can be caused by the reflected ray and its ground reflection, which cannot be resolved with the measurement bandwidth.
We model the wireless channel propagation using the two-ray ground reflection model [31]; it considers the direct path as well as the ground-reflected path between the source and destination.
The importance of the simulation length and of the ground reflection on the tones is demonstrated.
(vi) Ground reflection is not believed to have a significant effect on noise source location estimates in this study.
Some terrestrial radio links can operate by a combination of atmospheric wave propagation, surface wave propagation, ground reflection, and ionospheric reflection.
This paper presents a concept of an aircraft noise monitoring terminal (NMT) that reduces background noise and the influence of ground reflection, in comparison with a single microphone.
A new charging function according to the extended GTCS model is calculated, as well as the value of the ground reflection coefficient for both analyzed strokes.
By measurement and the modification of previous estimated irradiation data, which have not yet been verified, the regression equations of monthly slope irradiation ratio with no ground reflection were established.
As suggested by experiments in triggered lightning conditions or in measurements of simulated return strokes in the laboratory we assumed that the ground reflection coefficient depends on the current magnitude.
This paper considers the following practical extensions to the basic ECAS model: (a) out-of-phase primary sources; (b) three-dimensional primary sources; (c) ground reflection; (d) directional secondary sources and (e) wind effect.
The flanging effect has been described as a kind of ''whoosh" passing subtly through the sound.6.2The effect is also compared to the sound of a jet passing overhead, in which the direct signal and ground reflection arrive at a varying relative delay.
