摘要
天线下行组阵是提高深空测控能力的有效方法之一,已经在国外深空测控中开始应用。研究了天线下行组阵的几项关键技术,包括天线阵的布局和优化、天线阵的相位同步、天线阵的合成算法等,并构建了天线阵的试验验证系统,并利用嫦娥二号卫星进行了S频段的下行组阵试验验证,验证了工程的可实现性。
Downlink antenna array is one of the efficient methods to improve the ability for deep space exploration.The key technologies about the downlink antenna array are studied.These technologies are the distribution and optimization of antenna array,in phase and the combining algorithm.The verifying system of the antenna array is also constructed,with which the downlink antenna array is verified by utilizing the S band downlink signals of CE-2.It is practicable for engineering.
