摘　　要：针对间歇采样重复转发干扰对目标速度无法产生欺骗且容易被敌方识别的缺点,提出一种对脉压雷达的多相位分段调制干扰方法。对该方法的基本原理进行说明,建立干扰信号的数学模型,推导干扰信号的幅相特性和脉冲压缩结果,以采用线性调频信号的脉压雷达为平台,分析了该方法对脉压雷达的干扰效果。最后对相关干扰效果进行仿真验证,结果表明,与间歇采样重复转发干扰相比,所提干扰方法有较高干扰功率利用率,能够对目标形成灵活可靠的遮盖效果。The interrupted-sampling and periodic repeater jamming cannot generate deception on target speed and is easily recognized by enemy.Aiming at the disadvantage,a jamming method based on multiple phase sectionalized modulation is proposed to counter pulse compression radar.Its basic principle is illustrated,the mathematical model of the jamming signal is established,and the magnitude-phase characteristics and pulse compression result of the jamming signal are derived.Making pulse compression radar using linear frequency modulation signal as the platform,the jamming effects of this method on the pulse compression radar are analyzed.Finally,the simulation is conducted to prove the related jamming effects.The results show that the multiple phase sectionalized modulation jamming can achieve flexible and reliable overspread effects and have higher jamming power utilization compared with the interrupted-sampling and periodic repeater jamming.
