摘　　要：针对毫米波调频引信的数字射频存储转发、正弦调幅扫频、噪声调幅和噪声调频,提出了干扰方法。采用滤波分离差频信号,并从差频信号中提取多普勒信号参数的方法,将毫米波调频引信信号的差频测距结果以及多普勒信号作为引信启动的联合判决条件。仿真结果表明,对该体制引信施加正弦调幅扫频干扰和间隔转发干扰的欺骗效果明显,覆盖接收机的大功率噪声信号均能有效压制回波信号。The jamming techniques of digital radio frequency storage and forward,sinusoidal amplitude modulation sweep,noise amplitude and noise frequency for millimeter-wave frequency modulated proximity fuzes were proposed.The approach involved filtering and separating the beat-frequency signals,followed by the extraction of Doppler signal parameters from these beat-frequency signals.The beat-frequency range measurement results and Doppler signal parameters were used as joint decision criteria for fuzes’initiation.Simulation results demonstrated the significant deceptive effects of applying sinusoidal amplitude modulation sweep and spaced retransmission jamming to this fuze system.Moreover,high-power noise signals covering the receiver could effectively suppress echo signals.
