Radar Signal Research Based on JADE Blind Source Separation Algorithm

盲源信号分离技术在雷达抗干扰领域得到了广泛的关注和应用研究,所以对经过盲源分离的雷达信号的研究是至关重要的。分析了经过盲源分离的雷达信号存在幅度、相位的不确定性,并通过仿真分析得出了信噪比对盲源分离的影响。仿真结果表明,在信噪比满足一定的条件下,盲源分离能从强压制干扰中将信号分离。

Blind source separation technology has received wide attention and application research in the field of radar anti-jamming. So the study of signal based on blind source separation algorithm is crucial. The uncertainty of radar signal amplitude and phase are analyzed based on blind source separation algorithm and through the simulation analysis the influence of signal-to-noise ratio on blind source separation is obtained. The simulation results show that when the signal-to-noise ratio satisfies a certain condition and the blind source separation can separate the signal from the strong interference .
