1. A radar system comprising:
a set of transmitters including a first transmitter, a second transmitter, a third transmitter, and a fourth transmitter; and
a processor coupled to the set of transmitters, the processor configured to:
generate a first chirp of a set of chirps, in which outputs of the first and second transmitters are modulated by a first phase and outputs of the third and fourth transmitters are modulated by a second phase; and
generate a second chirp of the set of chirps, in which outputs of the first and fourth transmitters are modulated by the first phase and outputs of the second and third transmitters are modulated by the second phase.
