摘　　要：空间无源对抗被认为是避免严重国际纠纷的典型软对抗手段,其作战载荷可分为直接在空间平台上进行撒布作战的星载撒布器和天基干扰弹。以星载撒布器为研究对象,以无源物质在空间的最短飞行距离的计算结果为基础,分析了不同喷发角和颗粒半径条件下的对抗效果,从而为撒布器的优化设计提供理论基础。研究表明,在无源物质总体积相同的情况下,颗粒半径越小,沾染到敌星光学表面的无源物质越密集;颗粒间距小于0.5mm时,敌星的光学系统分辨率严重降低。就现有技术水平来说,降低颗粒半径到几百、几十微米是可行的。因此,提高喷嘴的雾化效果是撒布系统优化的关键。Space passive countermeasure is considered as a typical passive countermeasure method to avoid serious international dispute.Its payload subsystem is divided into two types： spreaders on satellite which can spread substance directly on satellite,and space-borne decoy rocket.For spreader on satellite,effect of the countermeasure was analyzed when strewing angle and radius of particles were different,basing on calculation of the shortest substance flight distance in passive countermeasure.This provided rationale for optimization design of spreader.The results show that the substance sticking on optical surface will be denser for smaller particles,when total volume is of the same.When the distance between particles is less than 0.5 mm,resolution of optical system reduces seriously.Radius of particles can be manufaotured reduced to hundreds or tens of micron for current technology,so improving atomization of nozzle is very important for optimizing system.
