摘　　要：卷积干扰以较高的能量利用率、较好的干扰效果及控制灵活等特点,成为对抗现代新体制相参雷达重要的干扰类型。文中基于干扰形成机理,分析比较了距离欺骗干扰和速度欺骗干扰分别与3类有源压制性噪声干扰卷积后形成的3类噪声卷积干扰,经过脉冲压缩前后的信号特征和干扰效果,利用噪声卷积干扰与常规脉冲卷积干扰在波形及相位上的差异,提取了用于识别的特征参数,并以模糊模式识别方法进行了识别。仿真结果表明,该方法有较高的识别率。Convolution jamming has become an important jamming for its high utilizable efficiency of energy, admirable interference effect and flexible control. Based on the forming mechanisms, the interference performances and characteristics of different kinds of noise convolution jammings is analyzed. According to the difference of waveforms and phases between noise convolution jamming and ordinary pulse convolution jamming, the character factors are extracted ,and then fuzzy pattern recognition has been used to recognize the types of convolution jamming. Computer simulation results show that the method is feasible and has comparatively high correction identification ratios.
