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 ...

Electromagnetic waves can be separated into seven distinct groups in the spectrum. Each group contains a range of frequencies. For example, visible light contains all the frequencies that can be ...

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