摘　　要：针对线性调频信号的脉内相干性,分析了移频干扰和卷积调制干扰的原理。由于传统移频干扰存在可被雷达准确识别的特征且难以对真实目标实施有效压制干扰的特点,论文给出了一种固定移频叠加卷积调制技术的组合型干扰样式。仿真实验表明,通过合理设置参数,移频卷积调制干扰能够对雷达产生压制性和欺骗性的双重干扰效果。Based on the pulse coherence of the LFM signal,the principle of shift frequency jamming and convolution modulation jamming are analyzed. Due to the traditional shift frequency jamming can be accurately recognized by radar and be difficult to effectively implement suppression jamming to real target,so a combined jamming pattern of fixed Shift frequency added convolution modulation jamming is proposed. Simulation experiments show that shift frequency jamming can produce the effect of repressive and deceptive jamming by setting the appropriate parameters.
