抗干扰技术在卫星通信工程中的应用研究

Application Research of Anti-Jamming Technology in Satellite Communication Engineering

在卫星通信工程中,日益严峻的信号干扰问题严重影响着信息传输的稳定性和安全性。针对这一问题,文章深入研究了抗干扰技术在卫星通信工程中的具体应用,探讨时频分析、阵列信号处理、自适应滤波以及前向纠错等多种抗干扰策略。经实验验证,实施抗干扰技术后,误码率(Bit Error Rate,BER)降至10-8,信噪比(Signal to Noise Ratio,SNR)平均增长了3.67 dB,性能远超未优化状态。

In satellite communication engineering,the increasingly serious problem of signal interference seriously affects the stability and security of information transmission.In order to solve this problem,this paper deeply studies the specific application of anti-jamming technology in satellite communication engineering,and discusses various anti-jamming strategies such as time-frequency analysis,array signal processing,adaptive filtering and forward error correction.The experimental results show that the Bit Error Rate(BER)is reduced to 10-8,and the Signal to Noise Ratio(SNR)is increased by 3.67 dB on average after the anti-jamming technology is implemented,and the performance far exceeds the non-optimized state.
