摘　　要：随着雷达干扰技术向全极化发展,厘清极化干扰机理对发展极化干扰技术至关重要。通过引入极化匹配系数,优化了雷达旁瓣对消多通道接收和处理模型,推演了变极化干扰条件下雷达旁瓣干扰对消比变化的数学模型,并给出了部分数学仿真校验和实测实验结果,可为量化分析变极化干扰对雷达旁瓣对消的干扰机理提供理论参考。As radar interference technology develops toward full polarization,it is crucial to clarify the mechanism of polarization jamming for the development of polarization jamming technology.This paper optimizes the multi-channel receiving and processing model of radar side-lobe cancellation by introducing a polarization matching coefficient.It also deduces the mathematical model of radar sidelobe interference cancellation ratio under variable polarization jamming conditions.In addition,partial mathematical simulation verification and actual test results are provided.The research contents can provide a theoretical reference for quantitatively analyzing the jamming mechanism of variable polarization interference on radar side-lobe cancellation.
