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。
Passive confrontation in space is considered to be a typical soft countermeasure against serious international disputes. Its combat payloads can be divided into spaceborne spreaders and space-based jamming bombs which are deployed directly on the space platform. Based on the calculation of the shortest flight distance of passive materials in the spaceborne spreader, the confrontation effect under different eruption angle and particle radius is analyzed, which provides a theoretical basis for the optimal design of spreader. The results show that the smaller the particle radius is, the more dense the passive material is to the optical surface of the enemy star when the total volume of the passive matter is the same. The resolution of the optical star of the enemy star seriously decreases when the particle spacing is less than 0.5mm. In the current state of the art, it is feasible to reduce the particle radius to hundreds, tens of micrometers. Therefore, improving the nozzle atomization effect is the key to optimizing the spreading system.
