Abstract
Aspects of the present disclosure are directed to radar apparatuses and methods involving the communication of data with radar signals. As may be implemented with one or more embodiments, a sequence of radar waveforms are transmitted as RF signals, the RF signals carrying communication data encoded onto a ramped radar carrier signal via phase-shift keying (PSK) modulation. Such modulation may utilize a modified, reduced-angle modulation with phase angles of less than π. Object-reflected versions of the RF signals are received and demodulated by deramping the received object-reflected versions of RF signals using a linearized version of the radar waveforms (e.g., without PSK modulation). This approach can mitigate compression peak loss.
