摘要

复杂电磁环境下卫星导航信号接收易受到严重干扰,抗干扰算法优化研究具有重要的应用价值。文中基于极化空时/空频多维域联合抗干扰技术,通过建立人机交互、信号生成、天线阵列接收、抗干扰算法和性能评估等5个模块,设计和开发了抗干扰算法仿真平台,并对空时和极化空时抗干扰算法的空间自由度、输出信干噪比、抗干扰前后频谱图和捕获结果进行了仿真分析,验证了平台对性能评估的有效性。仿真平台功能完善、配置灵活,显著提高了抗干扰研究的效率,为抗干扰算法优化提供了技术支撑。

Abstract

In complex electromagnetic environment, satellite navigation signal reception is vulnerable to serious interference. The optimization of anti-interference algorithm has important application value. Based on the multi-dimensional joint anti-jamming technology of polarization space-time/space-frequency, this paper designs and develops the anti-jamming algorithm simulation platform by establishing five modules: human-computer interaction, signal generation, antenna array reception, anti-jamming algorithm and performance evaluation, and simulates and analyzes the spatial degree of freedom, output signal-to-interference noise ratio, spectrum diagram before and after anti-jamming and acquisition results of space-time and polarization space-time anti-jamming algorithm. The effectiveness of the platform for performance evaluation is verified. The simulation platform has perfect functions and flexible configuration, which significantly improves the efficiency of anti-interference research and provides technical support for the optimization of anti-interference algorithm.

Key words： simulation platform; anti-interference; polarized space-time; spatial degree of freedom
