| 摘要: |
| 由于极化对目标物理特性的敏感性，使得其与信号的高分辨特性一起，成为雷达系统发展过程中信息开发和利用的主要方向，当前雷达干扰调制主要在时域、频域、空域和能量域进行，在极化域涉及较少，使得极化干扰手段存在着信息维度上的明显差距。本文首先对自适应旁瓣对消系统（Adaptive Sidelobe Cancellation，ASLC）的工作原理进行了分析，并在分析多点源干扰、异步闪烁干扰、变极化干扰等多种干扰对ASLC系统的干扰原理和干扰性能的基础上，提出了一种空域-极化域联合的异步闪烁干扰方法。试验结果表明，本文所提出的干扰方法相比于其余几种干扰方法对ASLC系统具有更好的干扰效果。 |

| Abstract: |
| Polarization has become a critical parameter in radar system development due to its sensitivity to target physical properties and its synergistic integration with high-resolution signal processing. This combination significantly enhances information extraction and utilization in modern radar systems. While current radar jamming techniques predominantly operate in the time, frequency, spatial, and energy domains, polarization-based jamming remains understudied, creating a notable research gap. Firstly, the operational principles of adaptive sidelobe cancellation （ASLC） systems are analyzed. Then, three jamming methods of multi-point source jamming, asynchronous blinking jamming, and polarization-varying jamming, and their respective impacts on ASLC performance are systematically evaluated. Based on these analyses, a novel jamming technique that jointly exploits the spatial-polarization domain through asynchronous blinking is proposed. Experimental results confirm that the proposed method outperforms conventional jamming approaches against ASLC systems. |
