Table 4: Means for horizontal polarization at different frequencies. Table 5, meanwhile, focuses on the parameters s\({}_{1}\) and s\({}_{2}\), which signify the standard deviations associated with our findings. A noteworthy outcome of our analysis is the discovery that the s\({}_{1}\) and s\({}_{2}\) parameters exhibit remarkable consistency, showing no significant variation across a spectrum of conditions, including different altitudes, polarizations, and frequencies tested. This consistency allows us to derive the standard deviation from a single, unified equation, greatly simplifying the overall calculation process. For additional frequencies within the range of 2 and 6 GHz, we can obtain values through interpolation, utilizing the parameters presented in Tables 3-5. It is crucial to apply these parameters with the specified precision in decimal points in all calculations to ensure accuracy.
