多源圆阵反向交叉眼干扰技术研究

Study of Multi-element Circular Array Retrodirective Cross-eye Jamming Technology

单脉冲雷达是一种兼顾抗干扰能力和测角精度的雷达,被广泛应用于火炮控制、目标跟踪和导弹制导等军事领域。目前交叉眼干扰是针对单脉冲雷达最为行之有效的干扰方法,其中多源圆阵反向交叉眼干扰(C-MRCJ)从理论上来说可以实现全方位稳定持续的干扰效果。针对C-MRCJ仍然存在特定情况下因测角误差为0而失效的问题,以六阵元的C-MRCJ模型,完成了单脉冲指示角和交叉眼增益的数学推导,并完成仿真验证。

The monopulse radar is a kind of radar with both anti-jamming ability and angle measurement accuracy,and is widely used in artillery control,target tracking,missile guidance and other military fields.At present,cross-eye jamming is the most effective jamming method for monopulse radar,and circularly multi-element retrodirective cross-eye jamming(C-MRCJ)can theoretically achieve stable and continuous jamming effects in all directions.In response to the problem that C-MRCJ still fails due to zero angle measurement error in specific situations,the mathematical derivation of monopulse indicated angle and cross-eye gain is completed by using the six-element C-MRCJ model,and the simulation verification is completed.
