随着对定位精度要求的逐渐提升 ,通道特性对跟踪结果的影响已不能忽略.针对通道非理想条件下BPSK-Like算法的跟踪性能展开研究 ,对BPSK-Like算法的处理过程进行建模 ,在此基础上推导了几种特殊通道影响下的码跟踪性能并进行了仿真验证.通道的非理想特性并不一定会对码跟踪精度产生影响 ,一般而言 ,相频响应非理想会对码跟踪偏差产生影响 ,但对码跟踪精度的影响有限 ;单纯的幅频响应非理想则不会影响码跟踪性能.%With a higher requirement on tracking performance ,the impact of an non-ide-al channel could not be ignored any longer .A BPSK-Like model w hich takes the non-ideal channel into consideration is set up and a theoretically analysis is given .T hree specific chan-nels are used in order to testify the correctness .It can be conclude that a non-ideal phase-fre-quency response may have obvious influence on tracking bias w hereas the impact on tracking accuracy is limited . Only non-ideal amplitude-frequency response may not influence the tracking performance .
