Title:
RADAR DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/112642
Kind Code:
A1
Abstract:
In a radar device of the present invention, a determination is made with respect to a first target candidate as to whether there exists a second target candidate associated with second target information that satisfies a first condition (S520). If a second target candidate exists, first target information corresponding to the first target candidate (subject target candidate) is compared to the second target information corresponding to the second target candidate (comparative target candidate) (S530). The "first condition" refers to a match in distance and relative speed. If, as a result of that comparison, the difference (G) between the power of the frequency peak corresponding to the subject target candidate and the power (i.e. signal level) of the frequency peak corresponding to the comparative target candidate is greater than a prescribed threshold (ThG) (S540: NO), then the subject target candidate is determined to be a false image (S560). On the other hand, if the difference (G) is not more than the prescribed threshold (ThG) (S540: YES), then the subject target candidate is determined to be an actual image (S580).
