摘　　要：盲抗干扰技术是一种利用盲源分离技术应对不可预知干扰的方法。在分析跳频盲分离抗干扰的技术文献的基础上,研究了基于时频分析的跳频盲分离抗干扰技术的性能。仿真结果表明,基于时频分析的盲抗干扰技术具有较好的抗非平稳干扰信号性能。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.
