摘　　要：双点源干扰是一种针对单脉冲雷达的有效角度欺骗干扰技术。现有文献均在单次回波情况下分析双点源相干及非相干情况下的干扰效果。而实际情况下,雷达在进行数据处理时,会进行脉冲积累处理,此时双点源干扰两点源信号间的相位会受到脉冲积累的影响,进而影响干扰效果。通过仿真分析,得出了脉冲积累处理下,单脉冲雷达受双点源干扰欺骗的角度不再稳定,而是在一定范围内波动的结论。Dual-source jamming is an effective monopulse radar jamming method. The jamming effect is analyzed under the condition of single echo. But in the actual situation, pulse accumulation is utilized in signal processing which would affect the phase between the dual-source jammers and finally affect the dual-source jamming effect. Simulation analysis indicates the deception angle of monopulse radar under dual-source jamming fluctuates in some range instead of keeping stable.
