PROBLEM TO BE SOLVED: To obtain a radar device for correctly obtaining, from received signals from a target at which the transmitted signals of a plurality of transmission antennas are reflected, the components originating in each transmitted signal that are used in beam synthesis.SOLUTION: A radar device is configured to be provided with: a plurality of transmission antennas for transmitting a transmission radio wave modulated by a pseudo-orthogonal signal; a reception antenna for receiving a reflected radio wave that is the transmitted radio wave reflected from a target; a reception unit for demodulating a received signal from the reflected radio wave received by the reception antenna; a signal separation processing unit for calculating the correlation of the received signal with each of the pseudo-orthogonal signals, and calculating a transmitted signal separation vector; a cross-correlation compensation unit for multiplying the inverse matrix of the correlation matrix of the pseudo-orthogonal signals by the transmitted signal separation vector, and calculating a transmission/reception propagation vector; a beam synthesis unit for calculating a composite beam on the basis of the transmission/reception propagation vector; and a target detection processing unit for detecting the target on the basis of the amplitude of the composite beam and a prescribed criterion.SELECTED DRAWING: Figure 1 |
