Abstract
It is an object of the present invention to provide a radar device and a velocity calculation method with which velocity can be calculated more accurately. A radar devicecomprises a transmitter, a first velocity calculator, a second velocity calculator, a first velocity corrector, and a second velocity corrector. The transmittertransmits pulse signals at two or more different pulse repetition frequencies. The first velocity calculatorcalculates a first Doppler velocity based on a first received signal. The second velocity calculatorcalculates a second Doppler velocity based on a second received signal. The first velocity correctorcalculates a first corrected Doppler velocity by folding correction of the first Doppler velocity. The second velocity correctorcalculates a second corrected Doppler velocity by folding correction of the second Doppler velocity.
