基于感知的航空通信系统试飞频率管理

摘要

信息技术的快速发展以及频谱用户大增致使无线电频谱成为非常紧缺的资源。航空电子系统设备量大，功能多，工作频段宽，电磁环境复杂，共址电磁干扰不可避免。科学规划试飞频率，规避干扰是试飞成功的关键。在分析航空通信系统技术特征的基础上，提出了基于频谱感知技术的航空通信系统试飞频率管理方法。该方法能够有效提高系统频谱利用率，并能支持试飞数据相容性分析及重建，提升航空通信系统试飞评估准确性。%With the fast development of information technology and the increase of spectrum user,spectrum has become a very rare resource. Due to large amount,multiple functions,wide operation band and complex electro-magnetic environment of avionics equipment,co-site interference is inevitable. It is a key point for a good plan of frequency in the flight-test. Based on the analysis of the avionic communication system,a frequency manage-ment method is introduced which uses the spectrum sensing technology. This method can improve the spectrum usage and support the analysis and rebuilding of the flight-test data,and improve the evaluation veracity of the avionic communication system′s flight-test.
