Abstract:

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 side-lobe 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.

Key words: radar jamming, cross-polarization, polarization time-varying, side-lobe cancellation, jamming mechanism

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。
