Abstract
In an object-detecting system using an FM-CW wave, points fto fcorresponding to detection peaks of a reflected wave from a road-side object such as guardrail and points mand mcorresponding to detection peaks of a reflected wave from a moving object such as a reflector of a preceding vehicle are indicated on two-dimensional coordinates along with the shape of a road ahead of a subject vehicle. Among the points fto f, mand m, the points fto fare determined as being provided by the reflected wave from the road-side object, and a distance from the subject vehicle to the object and a speed of the subject vehicle relative the object are calculated using the remaining points mand mexcluding the points fto f. Thus, only the moving object except the road-side object can be detected.
