Description

EME, often known as Earth-Moon-Earth is a way of communicating between two earth stations by using the Moon as a passive reflector. This presentation will show in detail how to design and build an SDR based radio with low noise amplifiers, power amplifiers and antenna systems to successfully communicate using the Moon as a reflector. Details will be presented on the RF and analog design, initial tests using GnuRadio, signal processing used, and final implementation of the complete system.
Real time Doppler frequency compensation and transmit/receive control will also be presented.
