Abstract

We have developed a 24GHz side-looking vehicle detection radar. A 24GHz front-end module and a novel signal processing algorithm have been developed for speed measurement and size classification of vehicles in multiple lanes. The system has a fixed antenna and FMCW processing module. This paper presents the background theory of operation and shows some measured data using the algorithm. The data shows that measured velocity of the passing vehicle is within the accuracy of 95% in single lane and the velocity of the vehicles in two lanes is within the accuracy of 90% by using variable threshold estimation. The classification of vehicle size as small, medium and large has been measured with 89% accuracy.

본 연구는 24GHz 측방설치 차량감지용 레이다를 개발하였다. 다차선에 존재하는 차량들의 속도 측정 및 차량 분류를 위해 24GHz 송수신 모듈을 개발하였고, 신호처리부에 새로운 신호처리 알고리즘을 적용하였다. 본 논문은 고정된 FMCW (Frequency Modulated Continuous Wave) 레이다 모듈로써, 동작원리 이론과 알고리즘에 대해 측정된 데이터를 나타내었다. 측정된 결과는, 가변 threshold 추출 방법을 이용하여 한 차선의 차량 속도에 대해 95%의 정확성과 두 차선에 대해서는 90%의 정확성을 보였다. 또한, 차량의 분류는 소형, 중형, 대형의 3종 분류로 약 89%의 정확성을 나타내었다.
