where [alpha] [member of][-[pi],[pi]), [beta] [member of][-[pi]/2, [pi]/2), [[alpha].sub.0] [member of] [-[pi],[pi]) and [[beta].sub.0] [member of][-[pi]/2,[pi]/2) represent the average values of azimuth and elevation angles, respectively, and k is an environmental coefficient which controls the scatterer spread around the mean value.
* generally, for the majority of the analysed cases, received differences are visibly elevation angle dependent (this applies to almost all GPS and GLONASS dPCC received for both L1 and L2 frequencies).
When estimating the rainfall using the reflectivity of the Doppler radar, it is common to use the echoes on the constant-altitude plan position indicator [28] at 1.5 km from the sea level or echoes at low elevation angles [29].
This tracking error transmission (i.e., tracking error of the EATD transmitted to dish concentrator) is related to the working elevation angle [beta] of the dish concentrator.

where [[theta].sub.s] is the squint angle of the monopulse beam, [[theta].sub.el] and [[theta].sub.az] are the differences of elevation angles and azimuth angles between the tracking axis and target, respectively, and [[theta].sub.A] is the angle difference between the beam maximum of quadrant 1 and target.
which is dependent on the elevation angle [phi] and azimuth angle .[theta] The diffuse-field transmission coefficient is finally calculated by integrating [tau] ([theta], [phi]) over [theta] and [phi]:
The analysis of measurement results shows that small-scale fading has high dependency on the flying height instead of the elevation angle or the distance.
[mathematical expression not reproducible]: The elevation angle rate and pitch angle rate, respectively (rad/s)
The Azimuth angle, [theta], was measured on the plane of the microphones, while the elevation angle, is measured with respect to its plane
Now let us consider AYthresh, which is the threshold value of elevation angle at MS.
