偽隨機(jī)噪音 - 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信號是經(jīng)過高速偽隨機(jī)序列和正弦載波二次調(diào)制的寬帶信號,因此具有周期平穩(wěn)特性,它在譜相關(guān)域表現(xiàn)為:幅頻特性在譜頻率等于零截面切片上包含了載頻和偽碼速率信息特征,在譜頻率等于載頻截面切片上包含了偽碼速率信息特征;相頻特性在循環(huán)頻率等于兩倍載頻截面切片上包含了載波初相信息特征。
