摘　　要：针对我国航天事业迅猛发展,在轨运行卫星数量急剧增加,有限的航天测控资源难以满足日益增长的测控需求的问题,基于网格球顶相控阵天线技术及现有地面测控站数学结构,设计了一种符合实际工程需求的半椭球面共形相控阵阵列地面测控站模型;采用STK/Matlab联合仿真的方法,以卫星两行数作为目标库进行数据采集,通过地球坐标系与子阵视线坐标系实现数据转换,对地面站选址与中国现役卫星之间的可见性关系进行了研究;仿真结果表明,纬度和经度均与卫星可见性成正相关关系,为全国范围内地面测控站工作积累科学数据,对后续相控阵阵列天线最大化利用提供数据基础与应用支持。With the rapid development of China's space industry,satellites in orbit has increased dramatically,and it is difficult for limited spaceflight measurement and control resources to meet growing demands for measurement and control,based on the geodesic dome phased array antenna(GDPAA)technology and existing mathematical structure of ground measurement and control stations,a semi-ellipsoidal conformal phased array ground measurement and control station model is designed to meet actual engineering needs;the satellite tool kit(STK)and Matlab joint simulation is used to collect the data with the satellite two-line orbital element(TLE)as the target library,and the data conversion is realized through the earth coordinate system and sub-array line-of-sight coordinate system,which investigates the visibility relationship with the ground station site and active satellites in China;Simulation results show that the latitude and longitude are positively correlated with the visibility of satellites to accumulate the scientific data for national ground station measurement and control stations,it provides a data foundation and application support for the maximizing utilization of subsequent phased-array antennas.
