针对盲分离和自适应旁瓣相消器(ASLC)两种抗干扰技术在实际中如何选择应用的问题,对盲分离和ASLC 的抗干扰性能进行了对比分析。在对盲分离和ASLC 抗干扰原理及信号处理技术研究的基础上,在多种场景及不同信噪比情况下对两种技术的抗干扰性能进行了仿真对比分析。通过分析,给出了不同干扰情况下抗干扰方法的选择依据,即ASLC 对于旁瓣干扰抑制更加有效,而主瓣干扰抑制方面盲分离技术更有优势。

With the aim to solve the problem on how to choose jamming suppression method between the blind source separation(BSS) and the adaptive sidelobe canceller (ASLC), the jamming suppression performance of BSS and ASLC are comparatively analyzed. Based on the study on the principles and signal processing methods of BSS and ASLC, the jamming suppression performance of BSS and ASLC under different jamming and signal-to-noise-ratio conditions are investigated by simulation. Through analysis, the theoretical basis for the choice of jamming suppression method under different scenarios is presented, i. e. , the ASLC is more effective in suppressing sidelobe jamming, while the BSS technique performs better on mainlobe jamming suppression.
