Abstract: PROBLEM TO BE SOLVED: To find the distance/relative speed of a target, based on a measured amount of frequency change (frequency sweeping speed) per unit time by measuring the amount of frequency change (frequency sweeping speed) per unit time of a frequency modulation signal. SOLUTION: A part 13 for measuring the amount of frequency change measures the frequency sweeping speed of frequency-increasing and frequency- decreasing periods, based on a beat frequency regarding a stationary object that is away by a known distance, and stores it at an actual measurement value storage part 15.
