| description | PROBLEM TO BE SOLVED: To enable a radar device to quickly and stably adapt to a radio wave environment and its change without largely changing the configurations.SOLUTION: A radar device for detecting a target on the basis of reflected waves generated when a radar signal is reflected from a target includes: a plurality of oscillators for generating a signal to be provided for the heterodyne detection of the reflected waves to be performed for detection and the generation of the radar signal; first control means for successively applying the plurality of oscillators to the heterodyne detection of interference waves to be distributed to a band where the distribution of the radar signal is permitted in a first period when the reflected waves to be provided for the detection of the target do not arrive to vary an oscillation frequency in the band; and second control means for maintaining the oscillation frequency of the specific oscillator to be provided for the heterodyne detection of the interference waves measured in the minimum level in the first period among the plurality of oscillators in a second period following the first period, and for applying a signal to be generated by the specific oscillator to the generation of the radar signal and the heterodyne detection of the reflected waves. |
