“以核反星”幽灵再现有矛必有盾,各种军用卫星的产生,导致反卫星武器的出现。在反卫星武器研究的早期,美国曾经尝试利用核导弹来杀伤卫星。它的原理是利用核弹头在卫星附近爆炸产生强烈的热辐射、核辐射和电磁脉冲等效应将卫星结构部件与电子设备毁坏,或致使其丧失工作能力。它的作用距离远,杀伤半径大,在武器制导精度较差的情况下仍能破坏目标。1962年7月,美国在太平洋的约翰斯顿岛上空400千米处进行了核武器爆炸试验。美军此次试验的设想是让带有核弹头的导弹在苏联卫星飞行的轨道附近 “The nuclear rebel” specter to reproduce the spear must shield, the emergence of a variety of military satellites, leading to the emergence of anti-satellite weapons. Earlier in the study of anti-satellite weapons, the United States had tried to use nuclear missiles to kill satellites. Its principle is to use nuclear warheads to explode in the vicinity of satellites to generate intense heat radiation, which can destroy satellite structures and electronic equipment or cause them to lose their ability to work. Its range of action is far, its lethal radius is large, and its target can still be destroyed under poor guidance of weapons. In July 1962, the United States conducted a nuclear explosion test at 400 kilometers over the Pacific island of Johnston Island. The tentative plan of the U.S. military is to have missiles with nuclear warheads nearby orbiting Soviet satellite flights
