For example, the first speed is a low speed, the second speed is a medium speed, and the third speed is a high speed.

Abstract: There is provided a radar device that calculates an angle of a target based on a phase difference between reception signals obtained by receiving reflected waves from the target. A transmitting unit alternately transmits first and second transmission waves having different beam patterns. A calculating unit calculates reception levels of the reception signals, and an estimate angle at which the target is estimated to exist. A first determining unit determines a degree of reliability of a level difference between the reception levels, on the basis of a comparison between the level difference with a reference value which is associated with the estimate angle in advance. A second determining unit determines whether the target exists at the estimate angle, on the basis of a determination result and the reception level based on the first transmission wave.
