2022,30(5):186-190
摘要：随着北斗短报文在航空飞行器跟踪监视的应用中，通信成功率直接决定了飞行器的实时跟踪监视效果。由于飞行器在飞行过程中可能会遇到各种复杂电磁信号干扰，北斗短报文通信成功率会随着电磁环境的变化而变化。为了提高通信成功率，利用北斗短报文接收和兼收两种通道进行了数据接收效果对比，并比较了两者之间的内容差异。基于信息融合理论的Dasarathy模型中的融合概念，使用北斗短报文的数据接收和数据兼收两种数据，提出了基于数据和特征组合的数据处理融合算法。该算法针对短报文数据特征进行融合，有效提高了北斗短报文的通信成功率，试验效果显著。

A data fusion algorithm based on feature combination for Beidou short message communication
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.
