中频带宽 meaning in English
if bandwidth
Examples
- The above waveforms discussed are to synthesize the wb or uwb with narrow band pulses . assuming the transmitting uwb linear frequency modulation ( chirp ) , dechirp processing is introduced , and the method involved to obtain high resolution by reducing the if bandwidth is presented . furthermore , dechirp processing used to sar imaging is discussed , and the processing steps are described
< wp = 4 >以上研究的两种信号形式都是通过窄带子脉冲串相参合成的方法来获得超宽带回波信号，本文还探讨了去斜率（ dechirp或stretch ）方法，分析了去斜率降低接收机中频带宽、 fft获得目标一维距离像的原理，并探讨了线性调频去斜率合成孔径雷达成像，给出了具体实现步骤。
