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).

Abstract: A frequency modulated continuous wave (FMCW) radar system includes an antenna array having C antennas where (C=A+B−1), a first integrated circuit (IC) device including A first sensor inputs, and a second IC device including B second sensor inputs. The first sensor inputs are coupled to a first A of the antennas, and the second sensor inputs are coupled to a last B of the antennas such that a common one of the first sensor inputs and a common one of the second sensor inputs are both coupled to a common antenna. Each IC device receives reflected signals on each sensor input, and mixes the reflected signals to associated baseband signals based upon a local oscillator (LO) signal. Each LO signal has a different phase shift. The LO signals are based upon a common LO signal.
