Abstract
A radar device is provided, which includes a first sector radar and a second sector radar, each including a code generator that generates two code sequences, a multiplier that multiplies the two code sequences by a coefficient sequence, wherein the two coefficient sequences of the first and second sector radars, respectively, are orthogonal to each other, a transmission signal generator that modulates the orthogonalized two code sequences, and an RF transmitter that transmits the modulated signal including the two orthogonalized two code sequences. At least one of the two orthogonal coefficient sequences for the first and second sector radars, respectively, includes one or more negative coefficients. The two orthogonal coefficient sequences include coefficients, which are identical to each other, in a first transmission cycle, and include coefficients, which are different from each other, in a second transmission cycle different from the first transmission cycle.
