• Under the condition of zero Doppler frequency shifts,this kind of"waveform pair"is equivalent to polyphase Barker coded waveform at costs of a small amount of loss in signal-to-noise ratio and widening of the bottom of mainlobe.
  在零多普勒頻移條件下，這類(lèi)“波形對(duì)”能以少量信噪比損失為代價(jià)使脈壓輸出波形的主旁瓣比等于碼序列的長(zhǎng)度，也就是說(shuō)，從主旁瓣比的角度講，這類(lèi)“波形對(duì)”可以等效為相應(yīng)長(zhǎng)度的多相巴克碼波形。
