متن کاملOn the meteor height from forward scatter radio observations
It is known from theory that, by means of a plasma physics approach, it is possible to obtain a simple formula to calculate the approximate height of a meteor (Foschini, 1999). This formula can be used in case of forward scatter of radio waves and has the advantage that it does not depend on the diffusion coefficient. On the other hand, it is possible to apply the formula to a particular type o...
متن کاملAx.25 Packet Radio Communications Using Meteor Scatter Propagation
Among radio amateurs digital meteor burst communication has been discussed for many years. Despite this, no experiments on amateur basis have (to the knowledge of the author) been performed in Sweden or elsewhere in the world. During the past two years several amateurs have reported the random appearance of AX.25 packets from very distant stations. The propagation of these packets can only be e...
متن کاملThe Harvard-MIT-NEMC Research Training Program in Medical Informatics.
The Harvard-MIT-NEMC Research Training Program in Medical Informatics brings together five separate research groups to provide a diversified training experience in Boston with sponsorship by the National Library of Medicine. This program offers predoctoral and postdoctoral programs, supplemented by many opportunities for collegial exchange and interaction among the groups.
متن کاملOn forward scatter of radio waves from meteor trails
In this paper, a new approach to forward scatter of radio waves from meteor trails is exposed. The attention is drawn to some macroscopic characteristics of a meteor plasma and it is shown that electron-ion collision frequency is not negligible, as commonly thought. A simple formula for calculations of radio waves maximum attenuation after the forward scattering is also pre-
