航天技术的快速发展使得在轨飞行器的数量迅速增长,传统上基于抛物面天线的测控技术已经不能满足未来全空域内同时多目标测控的需求,为此,提出了一种解决方案,采用共形阵列天线和数字多波束形成技术,在全空域内同时形成多个波束,每个波束指向一个测控目标,实现同时对多目标的测控. 根据提出的方案,研制了原理样机,进行了外场试验,结果表明样机的功能和主要技术指标与设计相符合,证明了技术方案的正确性.

The number of orbit aerocraft keeps increasing with the rapid development of aerospace technolo-gy. The mechanically controlled reflector antennas can not satisfy future demand for multi-target TT&C in hemispherical coverage. To solve the problem,a solution is presented. In this solution, conformal array an-tenna and digital beam forming( DBF) are adopted to form multiple beams in hemispherical coverage with each beam aiming at one target so that simultaneous multi-beam TT&C is realized. A principle prototype is developed and the field test is performed. The results show that the functions and main specifications of the principle protype satisfy design requirements,which proves the correctness of the solution.
