Abstract: A radar device includes a transmission antenna and a reception antenna having a plurality of antenna elements. The radar device switches the antenna elements in synchronization with a modulation cycle, thereby obtaining a reception signal.

Abstract: In a radar apparatus, IF beat signals are detected in a first section and a second section serving as two adjacent frequency up-modulation sections of a transmitted wave. Frequency conversions such as FFTs are performed on the IF beat signals so that the frequency spectra are obtained. Subsequently, peak frequencies are detected from the frequency spectra in the corresponding sections, and the phase difference between the peak frequencies is determined. Since the phase difference calculated in this manner depends on the relative moving distance ?r during the interval between the first section and the second section, the relative moving distance ?r, the relative distance, and the relative velocity at this moment can be calculated from the phase difference.

Abstract: A radar including a target measurement component, a differential velocity calculator and an overall velocity determination portion. The target measurement component transmits and receives an electromagnetic wave over a detection range repeatedly at measurement intervals to measure a position of a target in the detection range and measure a Doppler velocity of the target based on a Doppler shift of the electromagnetic wave reflected from the target. The differential velocity calculator determines a differential velocity of the target based on a change in position of the target during consecutive measurement intervals. The overall velocity determination portion determines a current overall velocity by calculating a weighted average of the Doppler velocity, the differential velocity, and a previously determined overall velocity.
