Abstract:With the application of Beidou short message in the tracking and monitoring of aviation aircraft, the success rate of communication directly determines the real-time tracking and monitoring effect. Since the aircraft may encounter various complex electromagnetic signal interference during flight, the success rate of Beidou short message communication will vary with changes in the electromagnetic environment. In order to improve the communication success rate, two different channels of Beidou short message were received and compared according to the data content. Based on the fusion concept in the Dasarathy model of information fusion theory, a data processing fusion algorithm based on data and feature combination is proposed using Beidou short message data reception and data collection. The algorithm integrates data characteristics, effectively improving the communication success rate of Beidou short messages. The test results are significant.
