Publication number: 20140285379Abstract: According to one embodiment, a monitoring device includes a monitoring antenna, a frequency converter, a filter, a detector, and an azimuth detector. The monitoring antenna receives a carrier wave, an upper sideband wave, and a lower sideband wave as a VOR signal. The frequency converter converts a frequency band of the VOR signal into an IF band. The filter includes passband. The passband removes a component of the lower sideband wave in the VOR signal. The detector detects a component of the carrier wave, and a component of the upper sideband wave from the signal output from the filter. The azimuth detector detects an azimuth based on the detected carrier wave component, and the detected upper sideband wave component.Type: ApplicationFiled: January 6, 2014Publication date: September 25, 2014Applicant: Kabushiki Kaisha ToshibaInventor: Yoshio KAWAGUCHI
