Modem technology has revived interest in the once popular area of meteor
scatter communications. Meteor scatter systems offer reliable
communications in the 500 to 2000 km range all day, every day. Recent
advances in microprocessor technology have made meteor scatter
communications a viable and cost effective method of providing modest data
rate communications. A return to the basic fundamentals has revealed
characteristics of meteor scatter propagation that can be used to optimize the
protocols for a meteor scatter link.
The duration of an underdense trail is bounded when its initial amplitude is
known. The upper bound of the duration is determined by maximizing the
classical underdense model. The lower bound is determined by considering
the volume of sky utilized. The duration distribution between these bounds
is computed and compared to measured values.
The duration distribution is then used to specify a fixed data rate, frame
adaptive protocol which more efficaciously utilizes underdense trails, in the
half duplex environment, than a non-adaptive protocol. The performance of
these protocols is verified by modeling. / Thesis (Ph.D.)-University of Natal, Durban, 1987.
