摘要
如何提高雷达的抗干扰能力一直是雷达信号处理的一大问题,问题的解决可以使雷达的检测和跟踪能力得以提高。在日趋复杂的信号环境下,传统的信号处理方法的局限性愈来愈大。本文通过对雷达信号处理过程和盲源分离技术的分析研究,提出采用基于盲源分离的多步处理抗干扰方法进行雷达抗干扰信号处理,可使雷达在复杂背景下具有更强的抗干扰能力。仿真试验结果证明这种新的雷达抗干扰处理方法是可行和令人满意的。
In radar system research, the performance of radar anti-jamming is a dilemma for a long time. If the problem is solved, radar will acquire stronger ability in signal detecting and tracking. The localization of traditional signal processing methods is become more tough under the complicated environments. In this paper, after analyzing the procedure of radar signal processing and the methods of blind source separation (BSS), a multi-step processing method based on BSS to radar anti-jamming is proposed. Simulation results demonstrate that the proposed method of radar anti-jamming is practically feasible.
