Abstract:
1. An apparatus that detects a moving object, comprising: an interface unit configured to receive, from a radar, measurement data that includes at least one distance from the radar paired with a reception level signal that indicates a strength of a radar wave reflected by a reflecting object located at the distance from the radar; a background data updating unit configured to detect the reception level signal that is greater than or equal to a first threshold from each of a plurality of the measurement data and acquire, for each distance from the radar, a background value that indicates a generation frequency for levels of the reception level signal that become greater than or equal to the first threshold; and a moving object detecting unit configured to detect the reflecting object as a moving object, the reflecting object having the background value that is less than a background value corresponding to a stationary object that is located in same distance of the reflecting object, wherein the reflecting object is one of a plurality of reflecting objects that are located at a distance that corresponds to the reception level signal that has a strength greater than or equal to a second threshold in the measurement data, the second threshold being higher than the first threshold.
