<p>Provided is a radar device capable of detecting a target at high resolution by a relatively small amount of computation without increasing the bandwidth of a transmitted signal. The present invention is provided with an FFT transformation means for Fourier-transforming a reception signal received by a reception means into frequency spectrum data, a peak frequency detection means for detecting the peak frequency of the frequency spectrum data obtained by the Fourier transformation, a data extraction means for extracting data in the vicinity of the peak frequency from the frequency spectrum data obtained by the Fourier transformation, an inverse FFT transformation means for inverse-Fourier-transforming the extracted data of the vicinity of the peak frequency into time-axis data, and a target detection means for detecting a target by performing high-resolution processing of the time-axis data obtained by the inverse Fourier transformation.</p> |
