Abstract
A radar device includes: a signal transmission unit for generating a MIMO signal including a plurality of pulse signals, and radiating the MIMO signal into space; a signal reception unit for receiving a reflection signal resulting from reflection, by a target, of the MIMO signal radiated from the signal transmission unit; a demodulation unit for demodulating the MIMO signal from the reflection signal received by the signal reception unit; a beam-forming unit for forming beams in a plurality of different directions, by multiplying the plurality of pulse signals included in the MIMO signal demodulated by the demodulation unit by a respective plurality of different weighting coefficients; a control unit for changing noise power included in each of the beams in the plurality of directions formed by the beam-forming unit, by shifting a phase of the MIMO signal generated by the signal transmission unit and adjusting the plurality of weighting coefficients on the basis of an amount of phase shift of the phase; and a target detection unit for detecting the target from each of the beams in the plurality of directions formed by the beam-forming unit.
