Research on Millimeter-wave Frequency Modulated Radio Proximity Fuze Jamming Techniques

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.
