RADAR TRANSCEIVER

WIPO Patent Application WO/2018/029954

A1

A phase shifter (22, 322, 422) shifts the phase of a modulated signal, an original signal for the modulated signal, or a frequency (fnc) signal generated by a noise cancellation signal generation unit (21) according to the frequency (Fmod-fnc, Fmod+fnc) of a reflection signal reflected and received from an obstacle when the modulated signal is transmitted by a transmission unit. A variable gain amplifier (25) amplifies or attenuates the amplitude of a noise cancellation signal generated on the basis of the output signal of the phase shifter. A coupler (26) couples the noise cancellation signal output by the variable gain amplifier to a reception signal received by a reception unit. On the basis of the signal resulting from the combination of the noise cancellation signal and the reception signal by the coupler, a control unit (5) controls the noise-cancellation-signal amplitude and phase shift amounts of the phase shifter and variable gain amplifier so as to cancel the reflection signal reflected from the obstacle. The control unit is provided with a storage unit (11) for storing the noise-cancellation-signal amplitude and phase shift amounts as parameters.
