民航地空通信干扰抑制系统的设计与实现

Design and Implementation of Interference Suppression System for Air-to-Ground Communication in Civil Aviation

在中国民航空管地空通信经常受到无线电干扰,无法保障正常通信。从根本上解决民航地空通信干扰问题,对于有效保障民航安全具有重要的意义。结合民航VHF通信干扰源的特点,将基于恒模阵列的自适应信号处理技术应用于地空通信干扰抑制中,设计并实现了自适应干扰抑制实时系统,取得了很好的干扰抑制效果。

In our country, the air-to-ground communication link often suffers from radio interference and could not work properly. Interference suppression is very important for the safety of civil aviation. In this paper, by utilizing the constant modulus property of most radio interference sources, the constant modulus array is proposed for the interference suppression and an experimental system was built. Experimental results are provided to illustrate the performance of the proposed method.
