常見(jiàn)例句

• The design of an airborne off-set parabolic reflector antenna with low sidelobes is discussed.
  介紹了機(jī)載雷達(dá)低副瓣偏餽拋物麪無(wú)線的設(shè)計(jì)。
• Using the conventional method of FFT to process such waveform would result in very high sidelobes and thus greatly debases the radar's performance.
