为争夺太空控制权，先进国家开展了广泛的反卫星激光**的研制，并初步具备反卫星能力。尤其以地基激光反卫**为主的定向能**，可对在轨卫星等目标进行软、硬破坏，其技术发展最为成熟，已成为未来外空攻防作战**系统的重要发展方向，受到世界各国的高度重视。从地基反卫星角度出发，重点对公开披露的美国地基反卫星激光系统进行了介绍和分析，介绍了地基反卫星激光系统的基本概念、操作概念、关键组成、试验模式和打击模式，对该系统涉及的关键性能参数进行了分析，为研究美国可能的地基反卫星激光**装备和卫星目标防激光打击提供参考。

In order to take control of the space, the advanced countries have already developed extensively anti-satellite laser weapon, and have the anti-satellite ability of first step. Ground-based anti-satellite laser weapon can perform soft and hard damage to target such as satellite in orbit. Its technology is the most mature and has become an important part of future outer space attack and defense combat weapon system. It is highly valued by all countries in the world. Considering the purpose of ground-based anti-satellite, the introduction and analysis of public reported American ground-based laser system were emphasized. The system concept, operational concept, key component, test mode and shooting mode were shown, and the key function parameters relevant to the system were also analyzed, which provided a reference for studying the United States possible anti-satellite laser weapon and satellite target defense from laser striking.
