n.波段

An achromatic conformal optical system working within infrared waveband was designed. 摘要設(shè)計(jì)了一個(gè)紅外波段消色差共形光學(xué)系統(tǒng)。

Operating in the heavy congested SW band,it is difficult for HFradars to find continuously useable waveband for signal modulation. 高頻雷達(dá)工作在十分擁擠的短波波段內(nèi)，可資用的能滿足信號(hào)調(diào)制的連續(xù)頻帶很難獲得。
