Claim 0:
1. A radar apparatus, comprising:
transmission circuitry, which, in operation, transmits each of a plurality of transmission signals using each of a plurality of transmit antennas; and
reception circuitry, which, in operation, receives each of a plurality of reflected wave signals using each of a plurality of receive antennas, the plurality of reflected wave signals being the plurality of transmission signals reflected by an object, wherein
the plurality of transmit antennas include at least one first transmit antenna and a plurality of second transmit antennas,
in a first direction, an absolute value of a difference between, a first spacing and a second spacing is a defined value based on a wavelength of the plurality of transmission signals, the first spacing being a spacing between the at least one first transmit antenna and a phase center of the plurality of second transmit antennas which are used for beam synthesis, the second spacing being a spacing between adjacent receive antennas of the plurality of receive antennas, and
in a second mode for detection within a range including a second distance shorter than a first distance, the transmission circuitry transmits the plurality of transmission signals using the at least one first transmit antenna and the plurality of second transmit antennas within a viewing angle of a first mode for detection within a range including the first distance.
