| 摘 要： | 通过对线性调频（LFM）信号子带分解的分析，提出了一种基于子带信号处理的时频单元剔除（SSP TFCD）LFM干扰抑制算法.这种算法充分利用了子带分解的时频定位特性，在干扰基本消除的同时保证了信号的失真度较小，因此它可以为系统带来较大的性能增益.仿真结果进一步证实本算法的性能优于基于子带分解的子带剔除算法(SSP SD).

| Abstract: | By analyzing sub-band decomposition of linear frequency modulation(LFM) signals,a subband signal processing based time frequency cell delete(SSP-TFCD) algorithm for LFM interference suppression is proposed.Because the algorithm makes good use of the time frequency localization feature of the subband decomposition,signal distortion is minimized when interference is deleted.Simulation results show that the proposed algorithm is superior to the SSP based subband deletion algorithm. |
