Claim:
1. A multi-sector radar comprising: a first sector radar including a first transmission-sequence generating unit that generates a first transmission sequence and a first transmitting unit that transmits the first transmission sequence; and a second sector radar including a second transmission-sequence generating unit that generates a second transmission sequence and a second transmitting unit that transmits the second transmission sequence, wherein the first transmission sequence is a sequence obtained by multiplying a first code sequence by a first orthogonalized code, the second transmission sequence is a sequence obtained by multiplying a second code sequence by a second orthogonalized code, an inner product sum of the first orthogonalized code and the second orthogonalized code is zero, a value obtained by multiplication of an ith element (V the fundamental sequence VV_2n includes a sub fundamental sequence VV_2(n−1) having a length of n, and the fundamental sequence VV_2n is equal to {VV_2(n−1), −VV_2(n−1)} or {−VV_2(n−1), VV_2(n−1)}.
