摘要：The present invention relates to a radar signal processor for detecting aparticular target located within a near range of a radar apparatus mounted on a vehicle,and a radar device incorporating the radar signal processing apparatus, and for movingobjects moving in low speed and moving objects with a slight movement Really

detectable. A method for mixing a radar signal with a transmission signal of atransmission wave to generate a beat signal andA first signal processing unit forobtaining frequency spectrum data by fast Fourier transformation of a beat signal andextracting the distance component data to a target, andIn the distance component data,the distance limiting part which takes out only the signal in the predetermined distancefrom the vehicle as the distance component data, andA buffer portion for storing thedistance component data for a predetermined period of timeA second signal processingunit for fast Fourier transformation of the distance component data stored in the bufferpartA target identifying means for identifying the presence of a nearby target as aDoppler component distribution in the near range, and.Diagram
