1. A radar apparatus, comprising:
a plurality of transmission antennas, which in operation, each transmits a transmission signal; and
circuitry, which, in operation, applies a Doppler shift amount to the transmission signal transmitted from each of the plurality of transmission antennas, wherein,
a plurality of the Doppler shift amounts has intervals set by unequally dividing a Doppler frequency range subject to Doppler analysis, and
the intervals of the plurality of Doppler shift amounts are set by adding an offset to each of equal intervals determined by dividing the Doppler frequency range by a number of the plurality of transmission antennas.
