Abstract: The present disclosure relates to a MIMO radar system, comprising a first beamforming network (6) comprising a first beam ports (7A) and antenna ports (7B), wherein the first beamforming network is configured to connect the first beam ports via the first antenna ports to the first antenna elements, wherein the first beamforming network is configured to generate for each first beam port a single beam pattern. The first antenna elements transmitting or receiving a single beam pattern selected from the number of single beam patterns, wherein the first antenna elements are spaced apart at a first distance selected to provide a beam pattern of the first antenna array essentially consisting of a plurality of single main lobes. The radar system also has a similar second beamforming network (8). The second antenna elements of which are spaced apart at a second distance, larger than the first distance, the second distance being selected to provide a beam pattern of the second antenna array essentially consisting of multiple main lobes and multiple side lobes.

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).
