摘　　要：与光学观测和无线电侦测等手段相比,雷达探测具有全天时、全天候的独特优势。文中详细分析了常用的两种卫星位置计算方法,系统阐述了空间监视雷达模型的性能模型、建模思路与构建过程。以北美防空联合司令部于2008年2月14日更新的在轨运行低轨卫星的轨道参数为基础,从经度和纬度两个方面探讨了探测雷达处于不同位置时其扫描波束的仰角对探测低轨卫星数目和次数的影响,并分析了不同仰角的扫描屏对单颗卫星的探测效能。Comparing with optical and wireless observation, radar detection is more preponderant because radar can work 24 hours a day and 365 days a year. In this paper, two methods of calculating position of satellite are analyzed in detail. The process of space target surveillance radar＇s model is introduced. Based on the parameters of low orbit satellites on orbit which are updated by NORAD on Feb 14, 2008, the effects of the elevation of scanning beam on the number and times of capturing satellites are discussed when the radar is in different positions. Finally, the detection efficiency of different scanning beams to one satellite is analyzed.
