A New RF Range Measurement Algorithm Using the Code Comparison

코드비교에 의한 새로운 전파형 거리측정 알고리즘

In this paper we propose a new RF range measurement method. Using two codes which have different chip rate, we transmit one code toward the direction of targets and calculate the distance by comparing it with the other untransmitted reference code. Because the measuring process is fully digitalized, the stability, resolution, flexibility, and compactness of the system are good. Some experimental results are provided to show the validity and the performance of the proposed method.
