Patent attributes
A radar apparatus includes: a transmission circuit; a reception circuit; a Doppler filter that discriminates baseband signals per distance and per Doppler frequency corresponding to the speed of an object; a threshold processing unit group that removes unwanted signals from output signals of the Doppler filter; and an estimation unit that estimates a position and speed of the object from the output signals removed of the unwanted signals. The threshold processing unit group includes threshold processing units corresponding to respective discriminated Doppler frequencies. Each threshold processing unit calculates a threshold value for a corresponding Doppler frequency using a peak value of the output signals in a range of distance corresponding to an object detection area, and determines output signals in the range that are no greater than the threshold value to be the unwanted signals.
