<p>A distance measuring apparatus comprising a transmission antenna (10) to radiate a transmission radio wave; a reception antenna (11) to receive a reflected signal from a target; an analog-to-digital converter (14) to perform an analog-to-digital conversion for converting a reception signal; and a signal processing unit (1) to process the converted signal and to detect the target, in which a transmission frequency of the transmission radio wave to be radiated is switched at a timing synchronized with a sampling frequency of the analog-to-digital conversion, the transmission frequency is switched in accordance with an arbitrary pattern within a frequency band, and the reception signal is rearranged in order on the basis of the arbitrary pattern at a time of the transmission to then be subject to a radar signal processing.</p> |
