摘要

太阳射电暴与航空电子系统的许多中断有关。这项工作的目的是制定太阳射电暴干扰阈值，该阈值考虑了航空相关仪器的技术规范、仪器工作频率以及行业规定的误差容限。太阳射电暴被认为是潜在的危险，当超过这些计算的阈值。特别注意无线电高度表，这是航空安全的一个重要组成部分。本文建议的vhf通信、GPS导航接收机和无线电高度计频率阈值为;分别为102,103和104 sfu。太阳射电暴干扰(对于104 sfu以上的太阳射电暴)显示在本工作中模拟的调频连续波(FMCW)无线电高度计的高度估计中导致大误差(64-251 m)。

The effects of Solar radio bursts on frequency bands utilised by the aviation industry in Sub-Saharan Africa.

Solar radio bursts have been associated with a number of disruptions in avionic systems. The objective of this work is to develop solar radio burst interference thresholds which account for the technical specifications of aviation related instrumentation, instrument operating frequencies as well as industry stipulated error tolerances. Solar radio bursts are suggested to be potentially hazardous when exceeding these calculated thresholds. Particular attention is paid to the radio altimeter, an important component in aviation safety. The thresholds suggested in this work for VHF communication, GPS navigation receivers and radio altimeter frequencies are; 102 , 103 and 104 sfu respectively. Solar radio burst interference (for solar radio bursts above 104 sfu) is shown to result in large errors (64-251 m) in the altitude estimates for the Frequency Modulated Continuous Waves (FMCW) radio altimeter simulated in this work.
