본 발명은 FMCW(Frequency Modulated Continuous Wave) 신호를 방사하고, 상기 FMCW 신호가 다중 표적에서 반사되어 되돌아오는 복수의 반사신호를 수신하는 송수신 모듈 및 상기 복수의 반사신호를 신호처리하여 추출된 복수의 표적정보에 각각 포함된 비트 주파수에 따라 허위 표적 여부를 추정하고 표적을 추적하는 신호처리 모듈을 포함하는 차량용 레이더 시스템 및 상기 차량용 레이더 시스템의 허위 표적 추정 방법을 제공한다.
The present invention relates to a vehicle radar system comprising: a transmitting/receiving module which radiates frequency modulated continuous wave (FMCW) signals, and receives a plurality of reflective signals returned when the FMCW signals are reflected from multiple targets; and a signal processing module which tracks the target according to a lot of target information extracted by processing the plurality of reflective signals. The signal processing module comprises: a signal processing unit which extracts the target information; a false target estimating unit which confirms whether or not at least one among the multiple targets is a false target based on the target information; and a target tracking unit which tracks a target which is not the false target among the multiple targets.
