동위상 채널만 사용하는 FMCW(주파수 변조 연속파) 레이더는 자동차 애플리케이션에 유리합니다. 이 레이더에서는 동위상 및 직교위상을 모두 갖춘 FMCW 레이더와 유사하게 여러 표적의 거리와 속도를 측정하기 위해 상향 처프 모드와 하향 처프 모드에서 비트 주파수 쌍을 검색해야 합니다. 위상 채널. 그러나 쌍을 검색하기 위한 조합 수는 동위상 및 직교 위상 채널을 모두 갖춘 FMCW 레이더의 조합 수보다 많습니다. 따라서 이들 쌍의 조합을 착각하여 잘못된 목표가 증가합니다. 본 논문에서는 잘못된 목표를 줄이기 위한 새로운 측정 알고리즘을 제안한다. 업 처프 모드와 다운 처프 모드의 차동 주파수 전력 스펙트럼을 이용하여 상대적으로 움직이는 타겟의 비트 주파수만을 추출합니다. 고정된 타겟과 움직이는 타겟을 분리하여 잘못된 쌍의 선택 수를 줄일 수 있습니다. 제안된 측정 알고리즘의 성능을 확인하기 위해 몇 가지 시뮬레이션을 수행했습니다. 표적 검출 확률의 큰 저하 없이 잘못된 표적 출현 확률이 감소하는 것으로 나타났다.

Abstract: A Frequency Modulated Continuous Wave (FMCW) radar using only in-phase channel is advantageous for automotive applications. In this radar, it is necessary to search the pairs of beat frequencies in an up-chirp mode and a down-chirp mode to measure the distances and the velocity of multiple targets similarly to a FMCW radar with both of in-phase and quadrature-phase channel. However the number of combinations to search the pairs is larger than that for the FMCW radar with both of in-phase and quadrature-phase channel. Therefore, false targets by mistaking the combination of these pairs increase. In this paper, we propose a novel measurement algorithm to reduce the false targets. We extract only the beat frequencies of the relatively moving targets using the differential frequency power spectrum of the up-chirp mode and the down-chirp mode. We can reduce the number of selected incorrect pairs by separating the stationary targets and the moving targets. We have conducted some simulations to confirm the capability of the proposed measurement algorithm. It was shown that the false target appearance probability is reduced without significant deterioration of the target detection probability.
