RADAR DEVICE

摘要

Provided is a radar device capable of improving both distance resolution and velocity resolution at the same time. The radar device is provided with a Fourier transformation section (11) for extracting a signal in a section having the same width as pulses included in a transmission wave from a received signal, executing Fourier transformation on the extracted signal, and generating the received signal after the Fourier transformation, a peak extraction section (14) for extracting the signal component at the frequency point where the value of power is maximized from the received signal after the Fourier transformation as a maximum power frequency component, a multiplication section (15) for selecting two arbitrary components out of a plurality of the maximum power frequency components obtained at the same time intervals as the intervals of the pulses included in the transmission wave to calculate a complex conjugate product, and a multiplied-value integration section (16) for adding the complex conjugate product calculated by the multiplication section to a plurality of times of observations to calculate the complex conjugate product after the integration, and a velocity calculating section (17) for calculating the Doppler velocity from the phase of the complex conjugate product after the integration.
