Classification: CPC G  H | IPC G  H

Claim 0:
1. A radar device comprising:
a signal transmitter configured to generate a multiple-input multiple-output (MIMO) signal including a plurality of pulse signals, and radiate the MIMO signal into space;
a signal receiver configured to receive a reflection signal resulting from reflection, by a target, of the MIMO signal radiated from the signal transmitter;
demodulation circuitry configured to demodulate the MIMO signal from the reflection signal received by the signal receiver;
beam-forming circuitry configured to form beams in a plurality of different directions, by multiplying the plurality of pulse signals included in the MIMO signal demodulated by the demodulation circuitry by a respective plurality of different weighting coefficients;
control circuitry configured to change noise power included in each of the beams in the plurality of directions formed by the beam-forming circuitry, by shifting a phase of the MIMO signal generated by the signal transmitter and adjusting the plurality of weighting coefficients on a basis of an amount of phase shift of the phase; and
target detection circuitry configured to detect the target from each of the beams in the plurality of directions formed by the beam-forming circuitry.
