Abstract
An inventive frequency modulated continuous wave (FMCW) radar system realizes both a quick detection of a higher relative speed provisional target and a sure detection of a smaller relative speed provisional target. The number of detection cycles used for a paring validity check, used to see if a detected target or a pair of frequencies is an actual target or a pair for an actual target, is set in response to the relative velocity enabling the target information for a target of higher relative velocity to be output more quickly.
