摘 要:针对日益发展的多星同时测控需求,给出了一种灵活的全空域多波束同时测控阵列天线实现技术。在分析国外GDPAA(网格球顶相控阵天线)相控阵技术的基础上,提出了子阵有源相控阵+多面数字波束合成的综合实现架构,比较了多面拼阵和球面拼阵工程实现的优缺点;并在单元天线建模的基础上对多面拼阵和球面拼阵进行了系统仿真,验证了其半球覆盖的波束性能和全空域覆盖的可行性。考虑工程实现,给出了多面拼阵的实现建议,并对其发展构思、预期性能和主要关键技术进行了探讨,最后进行了归纳总结。Flexible hemispherical simultaneous multi-beam TT&C (Tracking, Telemetry and Command) technology is presented to meet growing demands for simultaneous multi-satellite TT&C. Based on analysis of phased array technology used in GDPAA (Geodesic Dome Phased Array Antenna), an implementation structure combining active phased antenna array at sub-array level with multi-plane digital beam-forming is proposed. The advantages and disadvantages of multi planar array and dome phased array in engineering implementation are compared. System simu lation is done on multi-planar array and dome phased array based on unit antenna modelling. The feasibility of whole airspace coverage and the performance of hemispheric coverage beam are verified. To meet engineering require- ments, implementation suggestions on multi-planar array are proposed. Design features, approaches of develop- ment, expected performance and key technologies are discussed. Finally, a comprehensive summary is given.
