摘　　要：构建逼真的复杂干扰环境是进行全面、客观、科学雷达抗干扰性能评估的基础,针对新型制导雷达采用的旁瓣对消、旁瓣消隐、脉冲压缩、脉冲多普勒及频率捷变等抗干扰措施,传统干扰方式所构成的电磁干扰环境已不能满足其抗干扰性能评估的需求。依据制导雷达的技术特点,构建了针对其抗干扰措施的新型干扰方式,首先分析灵巧噪声干扰、间歇采样转发干扰及重复转发干扰产生机理的基础上,分别建立其数学模型进行仿真,并对不同参数下获得的干扰效果进行了对比,为制导雷达抗干扰性能评估电磁干扰环境构建提供了依据,有效满足了其评估需求。To build up vivid and complex interference environment is the basis to evaluate radar antijamming performance comprehensively and objectively. According to the different anti-jamming strategy of guidance radar,such as side-lobe cancellation,pulse compression,pulse doppler and frequency agility.Traditional jamming strategy is not able meet the need of anti-jamming performance evaluation. A new interference environment for guidance radar is built According to the technical characteristics of guidance radar. After analyzing the mechanism of smart noise jamming,interrupted sampling and repeater jamming（ ISRJ）,models and simulating all of them,the effect of each jamming is analyzed when changing parameter. The result provides a basis for the electromagnetic interference environment construct,and it meets the requirements of guidance radar antijamming performance evaluation.
