This paper proposes a method of estimating the parameters of a composite modulation fuze based on the frequency variation relationship and synchronization of the Duffing oscillator array. This is done by studying the characteristics of the Duffing oscillator output signal that is excited by the signals of the pseudo-code phase modulation and the linear frequency modulation (LFM) composite modulation fuze in order to meet the urgent need for jamming technology in the modern battlefield. Further, this paper proposes a design scheme of jamming waveform of composite modulation fuze based on the parameter estimation method. The parameter estimate approach suggested in this research, based on the Duffing oscillator, is compared to the standard parameter estimation method of composite modulated fuze signal through simulation experiments.Then, the effect of the jamming signal reconstructed on the composite modulation fuze is theoretically analyzed, and the semi-physical experiment is carried out to verify and compare with the traditional deception jamming method. The experimental results show that the parameter estimation method proposed in this paper can still obtain high precision parameter estimation results under −35 dB signal-to-noise ratio (SNR), and the reconstructed fuze jamming signal is superior to the other traditional deception jamming signals under −20 dB SNR.
