“智能卵石”（Brilliant Pebble）是美国劳伦斯·利弗莫尔国家实验室著名物理学家劳维尔·伍德博士为SDI计划提出的一种先进动能武器方案。它不仅代表SDI计划的动能武器正在向小型化、智能化方向发展,而且有可能改变目前的第一阶段战略防御系统结构方案,使之生存能力提高,而成本大大降低。因此,这一方案一经提出,就受到美国战略防御计划 Brilliant Pebble is a state-of-the-art kinetic weapon program proposed by Dr. Laurel Wood of the Lawrence Livermore National Laboratory for the SDI project. Not only is it a move toward miniaturization and intellectualization of kinetic-energy weapons on behalf of the SDI, it is also likely to change the current strategic structure of the first-phase strategic defense system to make it more viable and less costly. Therefore, once proposed, this plan will be subject to the U.S. strategic defense plan
