Abstract
In an FM/CW type radar device (R), when object candidate information storage means (M) stores as object candidate information a distance or a relative speed for an object that is determined based on a combination of peak signals on the rising side and the falling side in each detection area, if a difference in frequency between peak signaldetermined in a given detection area and peak signaldetermined in another detection area is no greater than a predetermined value and object candidate information due to peak signaland object candidate information due to peak signalstored in the object candidate information storage means (M) are substantially equal to each other, grouping means (M) carries out grouping of the two peak signals and, furthermore, object information calculation means (M) calculates the distance or relative speed for the object based on a combination of peak signals on the rising side and the falling side after the grouping processing. This enables the distance and relative speed of an object to be calculated with good precision by means of an FM/CW type object detecting apparatus while minimizing the amount of arithmetic processing and the processing time.
