There is provided an apparatus that detects a moving object which includes an interface unit to receive, from a radar, measurement data of a distance from the radar and a reception level signal reflected by an object located at the distance from the radar; a background data updating unit 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, 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; a moving object detecting unit to detect the object as a moving object, the object having the background value that is less than a background value of a stationary object that is located in same distance of the object.

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
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; anda 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. 2. The apparatus of claim 1, wherein the first threshold is set to be smaller than the second threshold only by a value corresponding to a variation range of the strength of the radar wave reflected by the reflecting object and received by the radar. 3. A method for detecting a moving object, comprising: receiving, from a radar, measurement data that includes at least one distance from the radar paired with a reception level signal that indicates the strength of a radar wave reflected by a reflecting object located at the distance from the radar;detecting the reception level signal that is greater than or equal to a first threshold from each of a plurality of measurement data and acquiring a background value that indicates a generation frequency of the reception level signal that is greater than or equal to the first threshold, for each distance from the radar; anddetecting 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. 4. A non-transitory computer-readable recording medium storing a computer executable program that, when executed, causes a computer to perform a method for detecting a moving object, the method comprising: receiving, from a radar, measurement data that includes at least one distance from the radar paired with a reception level signal that indicates the strength of a radar wave reflected by a reflecting object located at the distance from the radar;detecting the reception level signal that is greater than or equal to a first threshold from each of a plurality of measurement data and acquiring a background value that indicates a generation frequency of the reception level signal that is greater than or equal to the first threshold, for each distance from the radar; anddetecting 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.
