Tropospheric Scattering

 

Tropospheric scattering is a propagation mechanism of VHF (Very High Frequency) and UHF (Ultra High Frequency) radio waves. It occurs when radio waves are scattered by the atmosphere, allowing them to travel over the horizon. This can happen due to meteorological conditions such as temperature inversions, atmospheric turbulence, and other meteorological conditions.

Tropospheric scattering can cause radio waves to be reflected back to the Earth, allowing for communication over longer distances than line-of-sight propagation. This can be useful for communication in hilly or mountainous areas, where line-of-sight propagation is limited.

However, tropospheric scattering can also cause signal fading, multi-path distortion, and other signal impairments that can degrade the quality of the signal. These effects are more likely to occur during periods of high humidity, temperature inversions, and other meteorological conditions that can cause scattering.

In general, Tropospheric scattering is a less predictable propagation mechanism than line-of-sight propagation, and it can be affected by the weather and atmospheric conditions. To maximize the benefit of tropospheric scattering in a communication system, it is important to use the appropriate antenna and power

and to monitor the weather conditions in the area of communication.
