中文摘要： 针对升空平台通信面临的复杂电磁环境，研究静止升空平台通信中的动态多域（频率域、功率域、调制域、信道编码域等）抗干扰方法。提出了基于功率谱密度的干扰捕获和特征参数提取算法；提出了基于卡尔曼滤波的干扰行为预测算法；分别提出了基于功率谱统计特征参数和基于信号波形复杂性测度的两种模糊干扰样式识别算法。通过以上四个方面实现升空平台对干扰环境的认知。根据干扰认知结果、最小功率消耗决策准则及用户传输需求，分别提出了低复杂度固定干扰、跟踪干扰及扫频干扰环境下的多域抗干扰决策方法。仿真结果表明，本项目研究提出的干扰认知算法能够较好地实现对干扰环境的认知，多域抗干扰决策算法能够实现在不同干扰环境下对多域通信参数做出正确选择。该项目的研究，为升空平台的可靠有效通信提供了良好的理论基础。

英文摘要： The research has investigated dynamic multi-domain (frequency domain, power domain, modulation domain, channel code domain) anti-jamming method of immobile high-altitude platform communication focused on the complex electromagnetic environment. In the research, we proposed jamming capture algorithm and characteristic parameters extraction algorithm based on PSD, jamming behavior prediction algorithm based on Kalman filter, two fuzzy jamming pattern recognition algorithms based on statistic parameters of signal's PSD and complexity measure of signal's waveform respectively. High-altitude platform achieves cognition for jamming environment according to anti-jamming requirement by above-mentioned four aspects. According to jamming cognition results, decision rule of minimum power consumption and transmission requirement of user, we proposed low-complexity multi-domain anti-jamming decision-making methods under fixed jamming, followed jamming, and chirp jamming environment respectively. Simulation results shown that the proposed jamming cognition algorithms can achieve cognition for jamming environment precisely; multi-domain anti-jamming decision-making methods can select correct multi-domain communication parameters. The project will lay the theory foundation for high efficient and reliable communication of high-altitude platform in complex electromagnetic environment.
