[Simon Inns] just rolled out his latest project, a PIC based spectrum analyzer ... a bit of noticeable lag between the sound and the waveform representation on the graphic LCD.

The accuracy by which this can be accomplished is determined by the width of the spectrum of the reflected waveform. In order not to obscure the basic theory of how an airborne Doppler radar can be ...

Unlike OFDM and OFDMA, both of which modulate information within the time-frequencydomain, OTFS does so within the Delay Doppler domain.
