Claim 17:
18. A multiple-input multiple-output (MIMO) radar reception method, the method comprising
receiving, during a first receive time interval, a first receive signal corresponding to a superposition of reflections of concurrent first frequency-modulated continuous-wave (FMCW) radar signals transmitted, via a first subset of transmit channels of a plurality of transmit channels, with different first phase offsets among different transmit channels of the first subset of transmit channels in accordance with a first predefined code division multiplexing scheme,
wherein the first subset of transmit channels comprises a first transmit channel associated with a first phase modulation vector, and a second transmit channel, associated with a second phase modulation vector different from the first phase modulation vector; and

receiving, during a second receive time interval subsequent to the first receive time interval, a second receive signal corresponding to a superposition of reflections of concurrent second FMCW radar signals transmitted, via a second subset of transmit channels of the plurality of transmit channels, with different second phase offsets among different transmit channels of the second subset of transmit channels in accordance with a second predefined code division multiplexing scheme,
wherein the second subset of transmit channels comprises a third transmit channel associated with a third phase modulation vector, and a fourth transmit channel, associated with a fourth phase modulation vector different from the third phase modulation vector.
