高集成度星载相控阵数据处理单元设计与验证
|
摘要
相控阵天线由于其波束捷变特性而广泛应用于卫星的星间链路中。为实现星间的测距通信功能,需要信机与相控阵天线相互配合工作。而相控阵天线包括射频单元、控制器、信号分发模块、幅相校正模块等多个单元,导致星间链路存在系统体积、重量和功耗大、复杂性高等不足。利用一体化设计方法对相控阵天线控制器、幅相校正模块、收发信机的功能进行整合,给出了一种高集成度星载相控阵数据处理单元的设计方案及实验结果。实验结果证明了本方案的有效性。在保证系统性能的前提下,实现了系统的优化设计,大大降低了系统的复杂性并提高了系统的可靠性。
The phased array antenna is widely used in the inter-satellite link application because of the fast beam scanning character.The phased array antenna cooperated with the transceiver in the implementation of communication and distance measuremnet function.The phased array antenna consists of several modules,such as the RF module,controller,signal distribution module,amplitude-phase calibration module and so on.As a result,the inter-satellite link has the disadvantages of large volume and power consumption,heavy weight and high complexity.In this paper,a highly-integrated space-borne phased array antenna is proposed which can implement the function of transceiver,phased array antenna controller and amplitude-phase calibration module.The design scheme and experiment results are demonstrated.The experiment results verify the effectiveness of the design scheme.The system is simplized and optimized,the reliability is increased with the design scheme.
