Abstract: Various aspects of the disclosure are directed to the communication and processing of radar signals. As may be implemented in accordance with one or more embodiments characterized herein, receiver-generated phase lag is compensated by phase smoothing and pre-distorting radar signals. The radar signals are transmitted and reflections of those signals from various objects are processed by aligning respective waveforms in the reflections using group delay filtering, and differentiating the aligned waveforms via decoding. The phase lag compensation carried applied to the signals prior to transmission facilitates the differentiation (e.g., by facilitating alignment prior to decoding).
