차량용 근거리 계측을 위한 고분해능 FMCW 레이더의 구현
Implementation of High Range Resolution FMCW Radar for Short-Range Automotive Applications
초록
In this paper, a 24GHz FMCW radar system which measures the range and the relative velocity of a vehicle in close range is described. The intended ranging accuracy is 15cm and a possible system concept to achieve this objective is presented. The VCO nonlinearity correction method using a reference delay-line and the data extrapolation algorithms based on AR(autoregressive) model are applied. The implemented system shows relatively satisfactory results in ranging accuracy.
