Annotation

The study introduces a universal and comprehensive methodology for phase delay calibration, adjustment, and monitoring in meteor radars using aircraft coordinates obtained through Automatic Dependent Surveillance-Broadcast (ADS-B). For the first time, a step-by-step procedure is proposed, based on the analysis of residual path differences in radar interferometry (for meteor radars) combined with ADS-B data. The technique enables high-precision and reliable calibration of phase delays in the receiving channels of the meteor radar, accurate calibration of time delays for unbiased estimation of the range to meteor trails, refinement of antenna positioning including both horizontal alignment and vertical displacement relative to the reference center, as well as real-time detection of mismatch of receiving antennas to ensure continuous system monitoring and optimal performance. Experimental validation at the meteor radar of Kazan Federal University (KFU) demonstrated calibration accuracy within 0.5 degrees and antenna coordinate correction with less than 10�cm error across all axes. The results facilitate high-precision radar observations of meteor trails, identification of radiant points for individual meteors and meteor showers, and reliable reconstruction of atmospheric parameter profiles at meteor altitudes (80–100�km). Based on the successful experimental verification, the presented methodology can be recommended for implementation on existing and future meteor radars for analyzing both current and archival data, serving as an ultimate tool for the calibration of meteor radar observations.
