description | The present invention relates to a medium-frequency (MF) R-mode CW-based pseudo-range measurement device and method. An MF R-mode pseudo-range device may take over an RF R-mode signal wirelessly input from an MF R-mode transmitter (100) and reproduces each CW signal on the basis of a phase extracted from a CW signal with self-channel and adjacent channel interference sources removed from an MF R-mode signal, detects a phase difference between the reproduced each CW signal and a reference CW signal generated based on 1PPS, and on the basis of the detected phase difference, measure a pseudo-range using the MF R-mode signal by resolving the ambiguity of a CW pseudo-range by using a phase correction and CW increase/decrease algorithm. According to the above-described configuration, the present invention may take over an RF signal input wired or wirelessly from an MF R-mode transmitter and measure SNR and electric field strength, which are the quality of an MF R-mode CW signal through an RMS detector and an SNR detector on the basis of the pseudo-range measurement method.
본 발명은 중파 R-mode CW 신호의 의사거리 측정 장치 및 방법에 관한 것이다. 중파 R-mode 의사거리 장치는, 중파 R-mode 송신기(100, MF R-mode Transmitter)로부터 무선으로 입력되는 RF R-mode 신호를 인계받아 중파 R-mode 신호에서 자기 채널 및 인접 채널 간섭원이 제거된 CW 신호에서 추출된 위상을 기반으로 각각의 CW 신호를 재생하고, 이 재생된 각각의 CW 신호와 1PPS 기반으로 생성된 레퍼런스 CW 신호의 위상차를 검출하며, 이 검출된 위상차를 기반으로 위상 보정 및 CW 증감 알고리듬을 이용해 CW 의사거리의 모호성을 해결하여 중파 R-mode 신호를 이용한 의사거리를 측정할 수 있다. 전술한 구성에 의하여 본 발명은 중파 R-mode 송신기로부터 유·무선으로 입력되는 RF신호를 인계받아 상기 의사거리 측정 방식을 기반으로 RMS 검출기와 SNR 검출기를 통해 중파 R-mode CW 신호의 품질인 SNR 및 전계 강도를 측정할 수 있다. |
