远距离“低慢小”目标探测技术研究进展（特邀）

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.
