5[degrees] elevation angle
of the Guangzhou radar was about 400 m.
To accurately model the azimuth and elevation angle
of the 3D channel , we used the 3D coordinate system represented in Fig.
mathematical expression not reproducible]: The elevation angle
rate and pitch angle rate, respectively (rad/s)
Fig 6 and Fig 7 shows the characteristics of PPD assumed to be at constant distance and azimuth angle m with respect to the elevation angle
Because the distance of each PSP is fixed, the subtraction of the horizontal and vertical vertex positions between PSP#1 and PSP#7 yields azimuth and elevation angle
errors values for unreduced readings were increasing from the center toward the edges of the images, reaching up to 4 grades (Fig.
The blue markers indicate satellite tracks where the elevation angle
was between 10[degrees] and 20[degrees] (the receiver was configured to block the reception of satellites at elevation angles
Considering only specular positions of horns, an increase in the elevation angle
results in the Fresnel reflector providing better radiation efficiency than the metallic plane surface.
Indeed, gain increases with the frequency and depends on the elevation angle
(vertical/horizontal polarization or NVIS/ground-wave modes) and it is about 2 dBi at the highest frequency.
Subacromial impingement involves compression or mechanical irritation of the subacromial bursa, supraspinatus tendon, infraspinatus tendon, and/or long head of the biceps tendon between the coracoacromial arch and the humeral head (Figure 2(a))  and is purported to occur at lower humeral elevation angles
