• Ds signal is twice modulated with the rapid pseudorandom noise sequence and the carrier . so it appears cyclostationary . in the field of spectral correlation , ds signals appears its characteristic as fallows : for the amplitude of spectral correlation , the information of carrier frequency and pn code rate are contained on the spectrum frequency equal to zero sheet , and also the pn code rate is contained on the sheet of spectrum frequency equal to carrier frequency ; for the phase of spectral correlation , the information of carrier initial phase is contained on the sheet of cyclic frequency equal to double carrier frequency
  Ds信号是经过高速伪随机序列和正弦载波二次调制的宽带信号,因此具有周期平稳特性,它在谱相关域表现为:幅频特性在谱频率等于零截面切片上包含了载频和伪码速率信息特征,在谱频率等于载频截面切片上包含了伪码速率信息特征;相频特性在循环频率等于两倍载频截面切片上包含了载波初相信息特征。
