1. A radar device comprising:

  • a transmitter configured to transmit, at least, a first transmission signal generated on the basis of a first parameter for computing a relative velocity or a distance in a first detection range, and a second transmission signal generated on the basis of a second parameter for computing a relative velocity or a distance in a second detection range narrower than the first detection range;

    a receiver configured to receive the reflected waves of the first transmission signal from a target, as first reception signals, and receive the reflected waves of the second transmission signal from the target, as second reception signals; and

    at least one hardware processor configured tocompute a first distance in the first detection range on the basis of the first reception signals,compute a second distance in the second detection range on the basis of the second reception signals,compare the first distance and the second distance,if the first distance and the second distance overlap each other in a predetermined range, select the second distance as a measurement result of the distance of the target, andif the first distance and the second distance do not overlap each other in the predetermined range, select the first distance as the measurement result.
