A radar device includes a signal generating unit that generates a transmission signal; an output unit that outputs a transmission wave based on the transmission signal, at each of predetermined angles; a receiving unit that receives the reflected waves of the transmission wave from targets; and a deriving unit that derives information on the targets on the basis of reception signals related to the reflected waves. The signal generating unit generates a first transmission signal including at least one modulated signal as the transmission signal related to the transmission wave to be output at a first angle, several times, at intervals of a predetermined idle running time, and generates a second transmission signal including at least one modulated signal, as the transmission signal related to the transmission wave to be output at each of second angles different from the first angle, in each interval of the idle running time.

Radar device and transmission processing method of radar device

There is provided a radar device. A transmitting unit transmits first and second transmission signals generated based on first and second parameters for computing relative velocities in first and second detection velocity ranges, respectively. The second detection velocity range is narrower than the first detection velocity range. A receiving unit receives the reflected waves of the first and second transmission signals from a target as first and second reception signals, respectively. A velocity measuring unit computes first and second relative velocities in the first and second detection velocity ranges based on the first and second reception signals, respectively and obtains the velocity measurement result of the relative velocity of the target based on the combination of the first and second relative velocities.
