摘　　要：旁瓣对消(Sidelobe Cancellation, SLC)作为雷达抗干扰的重要措施之一,在电子对抗中起着重要的作用。为了深入分析不同参量对旁瓣对消性能的影响,越来越多的学者开展旁瓣对消技术研究并根据研究结果进行SLC系统改进或研究攻击旁瓣对消系统薄弱环节的新型干扰技术。目前,研究主要针对干扰个数、干扰形式、辅助阵元位置、通道一致性等因素对旁瓣对消系统性能的影响,而分析多干扰角度分布对旁瓣对消系统性能影响的较少。对此,首先建立SLC系统干扰抑制比数学理论模型,然后通过仿真分析多干扰角度分布对旁瓣对消系统性能的影响,为实际分布式支援干扰角度参数优化提供理论支撑。Sidelobe cancellation(SLC),as one of the important measures for radar anti-jamming,plays an important role in electronic countermeasures.In order to deeply analyze the impact of different parameters on the performance of sidelobe cancellation,more and more scholars are conducting research on sidelobe cancellation technology and improving SLC systems or researching new interference technologies that attack the weak links of sidelobe cancellation systems based on the research results.At present,scholars mainly focus on the impact of factors such as the number of jamming,jamming forms,auxiliary array element positions,and channel consistency on the performance of sidelobe cancellation systems.There is limited research on the impact of multi-jamming angle distribution on the performance of sidelobe cancellation systems.To address this,a mathematical theoretical model for the jamming suppression ratio of the SLC system is established first.Then,through simulation analysis,the impact of multiple jamming angle distributions on the performance of the sidelobe cancellation system is analyzed.Theoretical support is provided for the optimization of actual distributed support jamming angle parameters.
