摘　　要：在现代科技的快速发展中,“低慢小”目标的探测技术已成为民用及军事领域的关键技术。随着产业的升级转型,这些低空、慢速、小型目标的广泛应用迎来了新的挑战,尤其是在远距离探测方面。传统的探测技术,如声波、雷达、无线电、可见光、红外和激光雷达等,在远距离探测“低慢小”目标时仍面临诸多局限性。单光子激光雷达技术具有卓越的时间、空间分辨率、高灵敏度和远距离探测能力,为解决这一技术难题提供了新的思路和巨大潜力。通过深入分析远距离“低慢小”目标探测的难点,在对现有的传统探测技术进行了系统梳理与比较的基础上,进一步探讨了单光子激光雷达技术在未来“低慢小”目标探测领域的应用前景与技术难题,为系统性能提升和相关领域的技术进步提供支撑与借鉴。The rapid advancement of modern technology has made the detection of“low-slow-small”targets crucial in both civilian and military applications.With ongoing industrial upgrades and transformations,the widespread use of low-altitude,slow-moving,and small targets presents new challenges,especially in long-range detection.Long-range detection of“lowslow-small”targets using traditional detection technologies such as sonar,radar,radio,visible light,infrared,and lidar still faces many limitations.Single-photon lidar technology,with its excellent temporal and spatial resolutions,high sensitivity,and long-range detection capability,offers promising solutions to these technical challenges.This paper provides an in-depth analysis of the difficulties associated with long-range detection of“low-slow-small”targets and systematically reviews and compares existing traditional detection technologies.Furthermore,this study explores the application prospects and technical challenges of single-photon lidar technology in the future detection field of“low-slow-small”targets,providing support and guidance for enhancing detection system performance and advancing related technologies.
