In response to the problems of “premature explosion” and “misfire” caused by sweeping jamming in frequency modulated fuzes, a jamming elimination and signal reconstruction method combining constant false alarm rate (CFAR) detection and Burg extrapolation is proposed. To eliminate the impact of jamming on the fuzes, the technique uses a CFAR detector to detect the time-frequency distribution of the jamming and sets the signal energy of the jamming position to zero. This is based on the distribution differences between the target echo signal and the jamming of the beat signal in the time-frequency domain. A Burg extrapolation-based signal reconstruction technique is suggested to rebuild the target echo during the zeroing interval, aiming to address issues like partial fragment loss and the decrease in signal-to-noise ratio brought on by zeroing. The performance of the method is verified by simulation and actual measurement. The outcomes demonstrate that the anti-jamming method put forth in this research is capable of successfully suppressing sweep interference in the frequency modulated fuze beat signal.
