Disclosed is a radar apparatus including: a local oscillator for outputting a local oscillation signal; a transmitter unit; and a receiver unit. The transmitter unit includes: a transmission input configured to receive the local oscillation signal; and a transmitter configured to transmit a transmission signal based on the local oscillation signal that has been received via the transmission input. The receiver unit includes: a reception input configured to receive the local oscillation signal not via the transmission input; a receiver configured to receive a reflection wave based on the transmission signal; a cancel signal generator configured to generate a cancel signal based on the local oscillation signal that has been received via the reception input; and an adder configured to superimpose the cancel signal on a reception signal.
