RADAR DEVICE

摘要

Provided is a device equipped with a transceiver (20) whereby sweep signals subjected to FMCW modulation is transmitted at least twice, an FFT unit (32) whereby at least two rounds of sweep signals received in response to transmission from the transceiver are subjected to fast Fourier transforms, and an MRAV processing unit (35a) whereby beat frequencies corresponding to each of the at least two rounds of sweeps by the transceiver are calculated on the basis of at least two rounds of sweep signals obtained by performing Fourier transforms in the FFT unit, whereby velocities are calculated on the basis of beat frequency differences and time differences that are calculated, and whereby distances are calculated on the basis of velocities and beat frequencies that are calculated, thereby making calculations of distances and velocities of a plurality of targets.
