However , if bandwidth is more important than cpu time , adding a bzip2 compression layer might enhance the benefits 然而,如果帶寬比cpu時間更重要,那么添加bzip2壓縮層可能會使我們更加獲益。
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 >以上研究的兩種信號形式都是通過窄帶子脈沖串相參合成的方法來獲得超寬帶回波信號,本文還探討了去斜率( dechirp或stretch )方法,分析了去斜率降低接收機中頻帶寬、 fft獲得目標一維距離像的原理,并探討了線性調(diào)頻去斜率合成孔徑雷達成像,給出了具體實現(xiàn)步驟。
