RADAR APPARATUS |
| 摘要 |
A radar apparatus includes: a transmitter which, in operation, transmits, as radar transmission signals, code sequences including a plurality of complementary codes having a code length L in each transmission period; a receiver which, in operation, receives one or more reflected waves including the radar transmission signals reflected by an object and are analog signals; an A/D converter which, in operation, converts the one or more reflected signals into digital signals, which are discrete samples; and a calculator which, in operation, performs a first calculation of correlation between the discrete samples and the code sequence transmitted by the transmitter and a second calculation of correlation between the discrete samples and a partial code sequence obtained by extracting a code length L−Q (L>Q≧2) from a tail end of the code sequence transmitted by the transmitter, and that outputs one of a result of the first correlation calculation and a result of the second correlation calculation. |

1. A radar apparatus comprising:
a transmitter which, in operation, transmits, as radar transmission signals, code sequences including a plurality of complementary codes having a code length L in each transmission period; a receiver which, in operation, receives one or more reflected waves including the radar transmission signals reflected by an object and are analog signals; an analog-to-digital (A/D) converter which, in operation, converts the one or more reflected signals into digital signals, which are discrete samples; and a calculator which, in operation, performs a first calculation of correlation between the discrete samples and the code sequence transmitted by the transmitter and a second calculation of correlation between the discrete samples and a partial code sequence obtained by extracting a code length L−Q (L>Q≧2) from a tail end of the code sequence transmitted by the transmitter, and that outputs one of a result of the first correlation calculation and a result of the second correlation calculation. |
