(in Chinese) DOI: 10.12382/bgxb.2023.0369 http://doi.org/10.12382/bgxb.2023.0369 An anti-jamming method based on time-domain jamming cancellation and signal sparse reconstruction is proposed for the problem of “premature explosion” or “misfire” of continuous wave frequency-modulated (FM) fuzes under frequency sweeping jamming. The location and duration of jamming are detected through time-domain outliers, and the abnormal data are eliminated to suppress the impact of the jamming on the fuze. For the signal sparsity caused by jamming cancellation in time domain, an optimization equation for differential frequency signal reconstruction based on sparse regularization terms is established, and an ADMM-based iterative reconstruction algorithm is proposed. The performance of the proposed method is verified by using the simulated and measured data. The results show that the method can be used to suppress the influence of frequency sweeping jamming, accurately obtain the target range-velocity information, and improve the ability of FM fuze to resist the frequencys weeping jamming with a signal-to-noise ratio of -15dB and a zero sample rate of less than 70%.

This paper elaborates the research status of radio fuze anti-information interference from three aspects: single mode, multi-mode and cognitive technology with the introduction of the requirements of fuze interference. The existing anti-information interference methods have many problems, such as the deterioration of resolution, the inapplicability of signal processing methods and so on. Combined with the unique 'S'-shaped curved array pattern of frequency diverse array-multiple-input multiple-output (FDA-MIMO) technology, the anti-interference methods of FDA-MIMO technology is reviewed from three aspects: direction finding deception, low intercept point beamforming and anti-mainlobe interference. Each of the three methods is reviewed. Finally, the anti-information interference technology of radio proximity fuze based on FDA-MIMO is prospected.

The M-sequence pseudo-random code phase modulation and pulse Doppler combined fuze is designed based on the characteristics of M-sequence nonlinearity, which is complex in structure, huge number and difficult to be intercepted and reconstructed. The response expressions of each level in the detection process of fuze are derived theoretically, and the anti-jamming performance of M-sequence pseudo-code phase- modulated pulse Doppler combined fuze is quantitatively calculated by taking the processing gain as an index. The theoretical calculated and experimental results show that the M-sequence pseudo-random code phase-modulation and pulse Doppler combined fuze can further improve its anti-active jamming ability compared with m-sequence.

(in Chinese) DOI: 10.12382/bgxb.2022.0088 http://doi.org/10.12382/bgxb.2022.0088 An interference waveform pattern is studied for effective interference to UWB radio fuze. An interaction model of UWB radio fuze and periodically modulated interference signal are established. Based on the signal-to-interference ratio gain, the response characteristics of the fuze are analyzed under different noises, sine-wave amplitude modulation signals, sine-wave frequency modulation (FM) signals, and swept-frequency sinusoidal amplitude modulation (AM) signals. The simulated results are consistent with the theoretical values and verified by laboratory static confrontation tests. The results show that the swept-frequency AM interference is the most effective interference mode, and sine-wave AM interference is the best. By reasonably setting the parameters of the frequency sweep interference, the interference effect can be effectively improved.
