PROBLEM TO BE SOLVED: To improve detection accuracy of speed of a plurality of movable bodies.SOLUTION: A speed detection apparatus comprises: a speed detection unit for detecting, on the basis of a detection signal outputted by a Doppler sensor in accordance with travel speed of an object, a plurality of speeds of at least one of a first speed, which is the speed of a first speed detection target object, and a second speed, which is the speed of a second speed detection target object; and a speed determination unit for selecting, from among combinations of a first speed and a second speed in the first speeds and the second speeds detected by the speed detection unit, one combination on the basis of a reference value calculated by using the first speed and the second speed in each combination and a predetermined reference value and then outputting the first speed and the second speed in the selected combination as detection results, respectively. |
