Abstract/Summary:
Ionized trails are formed by particles entering the earth's atmosphere. The ionized trails act as a reflector and provide a meteor burst communications (MBC) link up to 2000 km. The long range forward scattering MBC has been researched for its potential partial replacement of satellite communications: it has found its niche market for commercial use in the mobile communications. Although a horizontal antenna is less susceptible to the manmade noise, it is easier to implement a vertical antenna on a transportation than the horizontal antenna. This triggered an investigation of the advantage or disadvantage of using the vertically polarized antenna over the horizontally polarized antenna.;This thesis covers the background of the MBC, the experimental set up, and the algorithm for echo detection. The result of the investigation is illustrated with various examples such as signal strength, and channel availability.
