基于改进型最大信噪比算法的抗压制性干扰研究

自雷达诞生以来，抗干扰能力一直是评价一部雷达性能的关键性指标，特别是随着战场电磁环境的日益复杂，雷达抗干扰问题变得尤其重要。针对抗压制性干扰，改进了传统意义上基于最大信噪比的盲源分离算法，提出了使用干扰重构算法取代滑动平均处理的方法，获得了比传统方法分离出质量更高的雷达信号，输出信号与源信号相关性更强。

Research into Anti-blanket Jamming Technology Based on Improved Maximum SNR Algorithm

Since there are radars ,anti‐jamming capability is always the key index to evaluate a radar , especially with the increasing complication of battlefield electromagnetic environment ,anti‐jamming problem of radar becomes particularly important .For anti‐blanket jamming ,this paper improves the blind source separation algorithm based on traditional maximum signal to noise ratio ,presents the method that uses jamming remodelment algorithm to replace the slide average treatment method , then gets the radar signal of better quality than by traditional method ,and the correlation between the output signal and the source signal is stronger .
