Linear Frequency Modulation (LFM) signal is a commonly used transmission signal of modern radar, which can effectively improve the range resolution and speed resolution. However, when Smeared Spectrum (SMSP) jamming is applied to the main lobe self-defense jamming, the jamming signal and the target height overlap in time domain, frequency domain and the airspace, which is an jamming pattern that can effectively combat LFM signals. In this paper, the difference of polarization information between the jamming signal and the target echo signal was used to construct a signal reception model of the hybrid polarization radar system. An anti-SMSP jamming algorithm based on jamming reconstruction and blind source separation was proposed to achieve jamming suppression. The simulation results show that the method proposed in this paper not only reduces the amount of calculation but also can effectively achieve jamming suppression when the jamming signal ratio is 25 dB.
