Doppler

The Ejs Doppler Effect model displays the detection of sound waves from a moving source and the change in frequency of the detected wave via the Doppler effect. In addition to the wave fronts from the source a graph depicting the time of emission and time of detection of each of the wave fronts...

This book presents a set of techniques useful in the construction of Low Earth Orbit (LEO) satellite communication systems, including the use of the Doppler shifts to aid communications.For a complete book description and ordering information, please visit...
