<p>PROBLEM TO BE SOLVED: To provide a moving-body distance measuring device configured to measure a distance to an object at an appropriate timing.SOLUTION: A moving-body distance measuring device to be mounted on a vehicle includes: a transmission antenna element 40 which transmits transmission waves of different frequencies depending on time; a plurality of receiving antenna elements 70a-70e for receiving each of receiving waves coming from an object which reflects the transmission waves; a first filter 50 which outputs a transmission signal of intensity corresponding to a frequency of the transmission wave; second filters 80a-80e which output receiving signals of intensity corresponding to the frequency of each of the receiving waves received by the receiving antenna elements 70a-70e; and measurement means 100, 110 which measure a distance to the object on the basis of an amount of change in frequency of the transmission wave in a predetermined time, and a difference between the intensity of the receiving signal of the receiving wave and the intensity of the transmission signal of the transmission wave transmitted at a receiving timing of the receiving wave.</p> |
