A Real Time Signal Processing Technique for the Code Correlation Short Range Measurement

코드상관 근거리 측정센서의 실시간 신호처리 기법

In this paper we describe a real time signal processing technique for the code correletion short range measurement sensor. Code correlation values are acquired via simple RC charging circuits within several tens of microsecond. Because the range measuring process is very fast and simple, the proposed technique is applicable to common near range targets as well as fast moving targets in real time. Some experimental results show the validity and usefulness of the proposed method.
