| 摘要 |
The invention provides a radar that transmits a radio wave and receives an echo of the radio wave, which is characterized by possessing ( 1 ) a reception means that detects a beat signal of the echo and the radio wave, ( 2 ) a first frequency analysis means that analyzes the beat signal into frequency components, and detects a peak signal of frequency spectra obtained thereby, and ( 3 ) a second frequency analysis means that analyzes the beat signal into frequency components with a frequency resolution different from that of the first frequency analysis means, and detects a peak signal of frequency spectra obtained thereby.
