Abstract

Abstract:

In order to suppress the smeared spectrum jamming on the linear frequency modulation radar, a fast jamming suppression method is proposed. Firstly, the sliding fast Fourier transform algorithm is used to estimate the arrival time of the jamming pulse and extract the pulse envelope. Secondly, fractional Fourier Transform is used to estimate the number of jamming sub-pulse, and the jamming delay, amplitude and phase are estimated by matched filtering the reference sub-pulse signal and reference jamming signal, which are constructed by using the number of sub-pulses. Finally, the jamming signal is reconstructed based on the parameter estimation results mentioned above, and the jamming can be suppressed by canceling the echo with the reconstructed interference signal. Compared with traditional methods, the proposed method has higher computational efficiency. Simulation results verified the effectiveness and robustness of the method proposed.

Key words: smeared spectrum (SMSP) jamming, jamming cancellation, parameter estimation, matched filtering
