摘　　要：针对扩频调相连续波体制低截获概率(LPI)雷达具有主动式隐身性、低截获概率和抗干扰能力强的特点,提出了一种结合平方倍频算法和DRFM(数字射频存储)技术的LPI雷达转发式欺骗航迹干扰方法。该方法能有效解决传统测频接收机无法检测隐藏在基底噪声下的LPI雷达信号和对LPI雷达进行转发式欺骗航迹干扰的问题。实际验证结果表明该方法在工程上可实现对LPI雷达多批目标的转发式欺骗航迹干扰。The spread spectrum phase modulation continuous waves LPI radar has the characteristics of active stealth,LPI（low probability of intercept） and strong anti-jamming ability.Aiming at these characteristics,is repeater deception track jamming method on LPI radar is based on the combination of the square-multiple-frequency algorithm and DRFM（digital radio frequency memory） technique.This method efficiently resolves the detection of the LPI radar signals hide below the basic noise which the traditional frequency measuring receiver cannot detect and figures out the repeater deception track jamming on LPI radar.The practical result shows that the method can realize repeater deception track jamming of batches targets on LPI radar in engineering.
