摘要
阐述了测距系统对测距伪随机码的一般要求,讨论了复合测距码的参数选择准则,介绍了复合测距码的构造原理,并提出了两种基于择多序列的改进复合测距码。
The general requirements of PN codes for ranging systems are prese nted,the selection principles of the composite ranging codes' parameters are dis cussed. The construction and performance of the composite ranging codes are surv eyed, and two kinds of improved composite ranging codes based on majority decisi on sequence are given in this paper.
