摘　　要：低空复杂风场通常指距离地面高度600 m以下,局地风速、风向快速变化的风场.其全天候大范围精细探测是雷达科学、气象学等领域的长期难题.低空复杂风场的全天候雷达精细探测涉及传感器设计、三维风场反演和全天候融合等关键技术.本文从激光雷达探测、微波雷达探测、全天候融合及特征危害提取等方面对风场探测的技术内涵及研究现状进行了梳理,并分析了发展趋势,为低空复杂风场全天候精细探测技术发展与应用提供参考.Low-level complex wind field usually refers to the wind field below 600 m,with rapidly fluctuating speed and direction.The fine-resolution and large-scale detection under all-weather conditions is a long-term challenge in radar science,meteorology,etc.,involving key technologies such as sensor design,three-dimensional wind field retrieval and in⁃formation fusion.This paper reviews the technical connotation and research status of wind field detection from the aspects of light detection and ranging(LiDAR)detection,microwave radar detection,all-weather data fusion and hazard feature ex⁃traction,and finally analyzes its development trend.We believe this work provides reference for the development and appli⁃cation of all-weather precision detection technology in low-level complex wind field.
