Meteor Scatter Project (2012-08-25)


This is the beginning (maybe the end ! ) of a project to create a high performance automated Meteor Scatter amateur communications mode. The first step is to learn as much as possible about the characteristics of the MS signal path and all its nuances. A simulator seemed to be a reasonable first step, since it would help define the parameters that have to be dealt with, as well as provide a needed test bed for various future implementations.

 The very nature of Meteor Scatter makes an accurate model difficult since just about all the characteristics of the event are random and unpredictable. However, I think the first order approximations made are sufficient to get started and a more detailed model can be tweaked as the project matures.

Only underdense trails are modeled since they seem to be the predominant and more useful events to base a communications system on.

Read the online help technical section for more details on the model used and other program details.

This Program is made available free of charge for amateur radio use only.
