| 摘 要： | 波束同步是主星带伴随分布式小卫星雷达系统的同步问题之一,分析了主星带伴随分布式小卫星雷达系统的波束同步问题。根据主星带伴随分布式小卫星雷达系统的特点,结合小卫星天线俯仰向可扫描、姿态可调节,提出了三种波束指向同步方法;分析了分布式小卫星雷达系统的波束覆盖同步问题,分别建立了主星和伴随分布式小卫星的波束覆盖数学模型;仿真分析“干涉车轮”,结果不仅证明这些模型的正确性,同时发现波束指向同步方法2有较好的优越性。

| Abstract: | Beam synchronization is one of synchronizations for spaceborne parasitic radar system,and this paper mainly analyzes this problem. Firstly,based on characteristics of spaceborne parasitic radar system and combined with scannable antenna and adjustable attitude of micro-satellite,three methods for beam pointing synchronization were presented.Then,beam area synchronization was analyzed,the models of beam area for the transmitting satellite and micro-satellites were established.Finally,the simulation of interferometric cartwheel as an example not only proves that these models are valid,but also indicates that the second method for beam pointing synchronization is much better. |
