Abstract
The target detection accuracy of a radar apparatus is improved. The radar apparatus includes signal generation circuitry, which, in operation, generates a first transmission signal and a second transmission signal, and transmission circuitry, which, in operation, transmits a multiplexed signal resulting from code-multiplexing the first transmission signal and the second transmission signal, wherein a modulation frequency of the first transmission signal at a first timing is identical to a modulation frequency of the second transmission signal at a second timing that is later than the first timing.
Claims15
A radar apparatus, comprising:
- signal generation circuitry, which, in operation, generates a first transmission signal and a second transmission signal per a transmission period;
- and
- transmission circuitry, which, in operation, transmits a multiplexed signal resulting from code-multiplexing the first transmission signal and the second transmission signal, wherein, per the transmission period, a modulation frequency of the first transmission signal at a first timing is identical to a modulation frequency of the second transmission signal at a second timing that is later than the first timing.
A radar apparatus, comprising:
- signal generation circuitry, which, in operation, generates a first transmission signal and a second transmission signal;
- and
- transmission circuitry, which, in operation, transmits a multiplexed signal resulting from code-multiplexing the first transmission signal and the second transmission signal, wherein different transmission delays are cyclically set for the first transmission signal and the second transmission signal for each transmission period corresponding to a code length of a code sequence used for code multiplexing for the multiplexed signal.
