A radar device transmits electromagnetic waves while scanning a detection area in a scan direction and detects an object in each of detection regions into which the detection area is partitioned in the scan direction. The radar device sets a continuous waveform of signal intensity of scan positions from data on the signal intensity of reflected waves individually from the detection regions and extracts a peak from the continuous waveform. A threshold value is set based on signal intensity at the extracted peak, and the scan positions are determined on both sides of the peak at which the signal intensity is equal to the threshold value as positions of both ends of the object in the scan direction.
