| 摘 要： | 为了自主完成诸如分布式雷达成像等任务,需要获得多个目标之间实时、高精度的相对距离,并进行数据交互。本文首先介绍了一种多目标相对距离自主测量的方法,分析了时钟基准频差对相对测量的影响;然后给出了基于扩频技术的相对距离自主测量设计方案,讨论了降低误差的途径;最后仿真分析了伪码和载波相位跟踪环路,给出了仿真结果。

| Abstract: | In order to accomplish the mission of distributing measurement, such as distributing radar imaging, it requires high-accuracy real-time multi-object ranging and communication. Firstly, the paper describes the principle and approach to determine relative range. The method demonstrated in the paper explains qualitatively how frequency accuracy affects ranging accuracy. Then, the paper develops the design method in detail using spread-spectrum technology, and the method for reducing error is discussed. Finally, code and carrier phase tracing loop are provided in simulation system, and some useful results are given. |
