Claim 0:
1. A method, the method comprising:
simultaneously transmitting, by a radar system, a first plurality of chirp signals with first multiple channels of the radar system and a second plurality of chirp signals with second multiple channels of the radar system that are different than the first multiple channels using a slow-time modulation process comprising:
modulating, using code-division multiplexing, the first plurality of chirp signals with a phase-modulation that is defined by a sequence of codes;
modulating the second plurality of chirp signals using:
code-division multiplexing with the phase-modulation that is defined by the sequence of codes; and
frequency-division multiplexing, based on a frequency shift that is defined by a frequency shift sequence;

responsive to simultaneously transmitting the first plurality of chirp signals and the second plurality of chirp signals, receiving, from one or more receive channels, a plurality of chirp returns corresponding to the first plurality of chirp signals and the second plurality of chirp signals; and
responsive to demodulating the plurality of chirp returns based on the sequence of codes, outputting, by the radar system, to an automotive system, radar data identifying objects inferred from the demodulated plurality of chirp returns.
