【摘要】 随着人类航天活动的日益增强,空间目标数量日益增多,空间碎片是人类航天活动遗弃在空间的废弃物,是空间环境的主要污染物。为保障我国载人航天、探月工程及应用卫星等航天活动安全,对空间碎片的探测较为迫切。本文首先综述了国内外空间目标监视系统的现状及发展趋势,并对监视设备进行了介绍。接着重点对空间目标环境进行了分析,从散射截面积、周期分布、偏心率分布、倾角分布、近地点远地点高度和半长轴等多个方面进行了归纳总结。然后研究了空间目标监视雷达的设计方法,分别从频段选择、极化方式的选择、雷达规模、阵面倾角和多目标能力等多个方面进行了分析,实现了空间目标监视雷达的设计方法。文中最后采用基于STK的空间目标监视雷达效能分析方法,对STK仿真软件及其模块进行了阐述,在此基础上进行了STK用于空间目标监视雷达搜索与跟踪能力仿真,对仿真过程进行了详细分析,并给出了相应的实现方法。
【Abstract】 The quantities of space debris are increased day by day with the human space activities increasing. Space debris are castoff abandoned by human space activities, they are the dominating pollutant. Exploration of space debris is necessary to ensure space activities safety, such as manned space, lunar exploration and application of satellite, etc.Firstly, space target surveillance system is summarized, and Surveillance Equipments are introduced. Then space target environment are analyzed, including scatter cross section, cycle distribution, inclination distribution, eccentricity distribution, perigee altitude, apogee altitude, and Semi-major axis. The design method of space target surveillance radar is studied, and a new design method is presented analyzing from several aspects, such as the choice of frequency band and polarization mode, radar scale, inclination of array and multi-objective ability. The method of space target surveillance radar of performance analyze is presented. STK simulation software and modules are introduced. The ability of searching and tracking are simulated based on STK. The process of simulation is analyzed in detail, and the implementation method is given.
