摘要
提出一种星载接收机结构方案。在接收机数量少于星载阵列天线阵元数的条件下,基于较少数量的接收机实现全部阵元输出信号的接收处理。阵列天线划分为虚拟子阵列,基于时分复用工作方式,通过程控交换矩阵与接收机连接,接收机对不同虚拟子阵列天线输出信号分时进行接收处理。给出了接收机结构框图、工作原理和性能仿真结果。
A satellite-equipped receiver architecture scheme is proposed. In the case that the number of receivers has to be less than that of array elements in an array-antenna, it can receive and process the impinged signals on all the array-elements. By dividing the large array antenna into a set of virtual subarray antennas, the receivers are connected to each subarray via a program-controlled switch based on time-division-multiplexing, and process the output snapshots on the subarray-antenna. The receiver＇s block diagram, flowchart and performance simulation results are given in the paper.
