MIMO RADAR APPARATUS AND MIMO RADAR METHOD

A radar apparatus includes a transmitter circuit. The transmitter circuit is configured to transmit, via a first transmit channel, a first sequence of FMCW radar chirps, and to transmit, via at least a second transmit channel, a second sequence of FMCW radar chirps concurrently with the first sequen...

Beschreibung
Zusammenfassung:	A radar apparatus includes a transmitter circuit. The transmitter circuit is configured to transmit, via a first transmit channel, a first sequence of FMCW radar chirps, and to transmit, via at least a second transmit channel, a second sequence of FMCW radar chirps concurrently with the first sequence of FMCW radar chirps. The radar apparatus includes a control circuit configured to control the first and second transmit channels to set phases of the FMCW radar chirps of the first and second sequences in accordance with a phase modulation scheme that includes a first unique phase code sequence assigned to the first sequence of FMCW radar chirps, and a second unique phase code sequence assigned to the second sequence of FMCW radar chirps. The first unique phase code sequence is combined with a scrambling phase code sequence. The second unique phase code sequence is combined with the scrambling phase code sequence.
