| 摘 要： | 卫星导航信号体制决定了导航系统的先天性能,是系统设计和升级过程中必须考虑的关键因素之一.本文提出了卫星导航信号体制的性能评估方法,并评估了Compass信号的性能.该评估方法包含了精度、抗干扰、抗多径、兼容性四个方面的内容,分别采用了Gabor带宽、解调抗窄带/匹配谱干扰品质因数、跟踪抗窄带/匹配谱干扰品质因数、多径误差包络、连续平均多径误差包络、谱分离系数、谱安全指数等指标来刻画这些方面的性能.基于我国对外公布的最新信号体制框架,将Compass信号体制和GPS,Galileo信号体制进行对比分析.分析结果表明：对于民用信号,Compass的性能最佳;对于特殊用户,Compass的精度、抗多径能力和GPS,Galileo相当,但抗干扰能力低于GPS和Galileo.这意味着Compass系统在未来的特殊条件下处于劣势.最后,给出了信号体制优化的建议.

| Abstract: | Signal structure is critical to the inherent performance of global navigation satellite system (GNSS), and it is one of decisive factors which must be investigated during system designing and upgrading course. This paper presents a kind of performance evaluation method, and evaluates the Compass signal performance. The method includes four aspects such as accuracy, anti-jamming, anti-multipath and compatibility. They are scaled with Gabor bandwidth, anti narrowband jamming merit factor and anti matched spec... |
