摘要
针对遥感卫星系统接收天线的小型化问题,提出了一种平面结构的遥感卫星接收天线系统设计。比较了不同形式天线的性能优劣,说明有源平面阵列形式的天线相较于传统的抛物面天线和相控阵天线来说,具有效率高、跟踪精度好等良好性能,同时具有小型化的优势。给出了有源平面阵列天线的系统组成,针对该天线的实现难点,即效率和跟踪问题,通过采用高效率的天线子阵形成有源子阵、采用陀螺稳定和相控电子波束扫描体制的方式予以解决。实测结果表明,该天线相较另外2类天线具有较高效率。
The design of a remote sensing satellite receiving antenna system with planar structure is presented to solve the problemof system size. Firstly,several antennas used in remote sensing satellite receiving systems are compared,and it is shown that the active planar array antenna has advantages such as high efficiency, high tracking accuracy and small size. The system composition of the antenna is given,and then the implementation challenges of high efficiency and high tracking accuracy are addressed by means of efficient antenna arrays and phased beam scanning. Finally,it is concluded that the antenna is more efficient than other two types of antenna.
