Abstract
A radar apparatus includes: a transmitting antenna; a receiving antenna; transmitting circuitry; receiving circuitry; a storage; and control circuitry which selects one of a plurality of spread codes. A radar signal includes a plurality of periodic frames. Each of the frames includes first and second segments. The first segment includes a first spread signal which is obtained by multiplication of a predetermined reference signal by at least a part of the selected spread code. The second segment includes a second spread signal which is obtained by multiplication of the identification code by at least the part of the selected spread code. The control circuitry calculates a first correlation value between a received radar signal and the first spread signal, calculates a second correlation value between the received radar signal and the second spread signal, and selects another one of the plurality of spread codes on a basis of temporal positions and magnitudes of peaks of the first and second correlation values in each frame.
