Beschreibung
Zusammenfassung:	A detection device detects a target based on a reception signal obtained from a reflection signal of a transmission signal. The detection device includes a Doppler frequency component generator that acquires a Doppler frequency component that indicates the amplitude level of a reception signal, for at least one Doppler frequency, based on the reception signal, a region identifier that identifies a first region and a second region that is outside the first region, based on the value of the amplitude level and the increase rate in the amplitude level, a second-Doppler frequency component suppressor that suppresses the Doppler frequency component of an unnecessary signal, out of the Doppler frequency component corresponding to the second region, and a combiner that combines the Doppler frequency component corresponding to the first region outputted from the region identifier, and the output of the second Doppler frequency component suppressor.
