| Abstract: | Based on the characters of LFM-BC waveform, the simulation model of radar pulse compression system was built. By simulation, the jamming effects of such four jamming types as range deception jamming, frequency-shift jamming, range and frequency-shift dimensions deception jamming and multi-correlative false target deception jamming on LFM-BC signals were compared. Then the influence of various frequency-shift on main lobe amplitude, -3dB main lobe width and the ratio of main lobe and side lobe, was analyzed, over which the related conclusions were drawn. |
