It also be the first one of the fractional transform in the interference suppression domain, there was algorithm of the time-domain elimination, the suppression of special broadband interference-linear frequency modulation interference in fractional Fourier domain. But this algorithm has some shortage. 它也是首先在干扰抑制领域得到应用的分数阶变换,在时域对消、分数阶Fourier域抑制特殊的宽带干扰&线性调频干扰(FMI)上都已经有相应的算法提出,但这些算法都存在着多种不足。
The analysis of adding windows characteristics of linear frequency modulation interference in the domain of fractional Fourier transform shows that the energy of interference is relatively more concentrated. 通过对分数域线性调频干扰(FMI)加窗特性的分析表明,干扰能量相对更集中。
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. 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。
