摘要
气象要素作为表征大气物理状态和天气现象的重要指标,其系统性观测与分析对人类理解及预测天气变化具有至关重要的作用。随着全球气候变化加剧极端气象灾害频发,各个国家越来越重视对气象要素的监测。相干激光雷达作为激光遥感技术中的一种,能够非接触、高效、准确地探测多种气象要素。针对相干激光雷达的多气象要素一体化探测问题,首先阐述了相干激光雷达的原理及技术特点,其次从相干激光雷达探测多气象要素方面介绍了其研究进展,特别是相干激光雷达已经从单一气象要素探测向多气象要素同步探测转变,最后对相干激光雷达气象探测技术的未来发展进行了展望。
Meteorological parameters,as critical indicators characterizing atmospheric physical states and weather phenomena,necessitate systematic observation and analysis to enhance human understanding and prediction of weather dynamics.With global climate change exacerbating the frequency of extreme meteorological disasters,international efforts to refine monitoring capabilities have intensified.Laser remote sensing technology,particularly coherent lidar,represents an advanced methodology for non-contact,efficient,and precise detection of multiple meteorological parameters.This article addresses the integrated detection of multi-meteorological elements via coherent lidar systems.It first elucidates the operational principles and technical characteristics of coherent lidar,emphasizing its heterodyne detection mechanism for aerosol backscatter signals.Subsequent sections review research advancements in multi-parameter detection,highlighting the paradigm shift from single-parameter measurements to synchronous multi-parameter acquisition.Finally,future developments in this field are discussed,including potential enhancements in spectral resolution,signal-to-noise ratio optimization,and multi-sensor fusion strategies to address complex atmospheric profiling challenges.
