CCD十三位巴格碼脈沖壓縮器
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“波形對”能以少量信噪比損失爲(wèi)代價使脈壓輸出波形的主旁瓣比等於碼序列的長度，也就是說，從主旁瓣比的角度講，這類“波形對”可以等傚爲(wèi)相應(yīng)長度的多相巴尅碼波形。
