摘要
多侧音测距广泛应用于USB统一测控系统中,载波及侧音跟踪状态对距离结果有重要影响。在距离捕获阶段,载波及侧音跟踪状态影响距离匹配结果,在距离跟踪阶段,载波或侧音失锁会造成距离结果跳周。结合多测距音测距原理对捕获阶段和跟踪阶段中出现的问题进行了深入分析,在测距过程中利用速度值对距离结果进行实时检测及递推的方法可以解决上述问题,并结合工程应用数据对问题解决方法进行了验证。
The multi-Tone ranging is the most widely used in unified S-band ranging system. The precision of carrier tracking and Tone tracking will decide measurement accuracy. During ranging tracking stage, the carrier and tone unlocking can make large ranging results. In this paper, according to the mnlti-tone ranging theory, the matter occurring in acquiring and tracing stage is deeply analyzed. The real-time recurrence of velocity algorithm available for ranging matter is verified by the practical engineering data.
