Smeared spectrum (SMSP) jamming is a kind of correlative blanket jamming to linear frequency modulation (LFM) signals. According to the periodicity of SMSP jamming sub-pulse, a jamming suppression method based on jamming reconstruction and kurtosis maximum is proposed. Firstly, the period of sub-pulse is estimated by utilizing the autocorrelation method, and the frequency modulation rate is computed based on the principle of SMSP jamming. Then we can reconstruct each jamming sub-pulse while the phase is still unknown. Secondly, each reconstructed sub-pulse is set with different phase, and then the conjugate multiplication between received signal and reconstructed signal is done. The initial phase of jamming signal can be achieved by analyzing the result of conjugate multiplication. Finally, the jamming suppression factor is computed based on the kurtosis maximum and then the jamming can be suppressed. The simulation results show that the proposed method can suppress SMSP jamming efficiently, the SIR can be more than 20 dB after jamming suppression, and it can maintain high signal-to-interference and noise ratio gain even when the noise and phase error exist.
