wide-band signals

基本解释

In multipath environments, ultra-wide band signals suffer from severe time dispretion.
超宽带信号经多径信道传播会产生严重的时间弥散。
On the basis of the waveform storage method, a digital generation system scheme for ultra wide-band LFM pulse compression signals is proposed in this paper.
对线性调频（LFM）信号的三种主要数字产生方法进行分析，提出一种基于波形存储直读法的超宽带线性调频脉冲压缩信号数字产生系统方案。
Section short EP is advised to realize DOA estimation of wide-band FM signals, while DFT-EP can also be used to resolve the same problem in frequency domain.
提出了分段短时演变谱方法，并用之解决了宽带FM信号的测向问题。利用频域聚汇和DFT演变周期谱方法提出了另一种宽带FM信号到达角估计的新思路。

宽带信号
The instantaneous bandwidth of digital RF memory(DRFM) suffers from the constraint of the sampling rate of digital devices,it is necessary to find alternative technique to store wideband signals.
单信道数字贮频的瞬时带宽受数字器件采样率限制,已不适应宽带信号的存贮。
