脉冲压缩技术在相干激光雷达中的应用研究

摘要

The pulse compression technology has been widely used in the field of the microware radar and wireless communications,but it uses less in the field of coherent laser radar,especially coherent laser ranging.The pulse compression technology was used in the system of the coherent laser radar.The theory and performance of pulse compression coherent laser radar were analyzed.The analysis results show that the pulse compression technology can significantly improve the performance of coherent laser radar.%脉冲压缩技术在微波雷达、无线通讯领域有着广泛的应用,但在相干激光雷达特别是相干激光测距领域应用较少.本文将脉冲压缩技术应用于相干激光雷达系统中,对脉冲压缩相干激光雷达进行理论分析和性能分析,分析可见脉冲压缩技术可显著提升相干激光雷达的性能.
