Abstract
A radar has a transmission section, a reception section that receives a reflected wave of the transmission wave, a transmission switch section, a delay section that delays a predetermined timing, a reception switching section, a difference processing section, and a calculation section. The transmission section switches between a first frequency and a second frequency to transmit a transmission wave having one of the frequencies. The transmission switch section switches between turning-on and turning-off of an operation of the transmission section at the predetermined timing. The reception switching section switches between turning-on and turning-off of an operation of the reception section according to the timing delayed. The difference processing section outputs a difference between the transmission wave and the reflected wave. The calculation section calculates a distance on a basis of a delay amount, when a detection waveform has a difference frequency between the first frequency and the second frequency.
