| Abstract: | Blind anti-jamming technique exploits the technological superiority of blind source separation （BSS） to deal with the unpredictable interference. Based on the analysis of Literature about frequency-hopping blind separation antijamming technology, the performances of frequency-hopping blind separation anti-jamming technology based on timefrequency analysis are researched. The simulation results show that blind anti-interference technique based on time-frequency analysis has good anti-interference performance for non-stationary interference signal. |
