| Abstract | 面向天文信号实时处理的需求,搭建了基于ROACH2的射电天文数字终端实验平台。利用MATLAB, Xilinx等开发环境进行仿真,取得了原始实验数据;利用CASPER硬件平台实现了信号控制和预处理,并通过高速以太网将数据包传输至计算服务器进行后处理。搭建的实验平台实现了仿真、编译、运行的完整流程,为天文信号实时处理研究提供了良好的实验环境。 |
| Other Abstract | An experimental platform of radio astronomy digital backend based on ROACH2 was built for the real-time processing requirements of astronomical signals.Using MATLAB,Xilinx and other development environments to simulate the process of astronomical signals,and the raw data were obtained;the signal control and pre-processing were realized by CASPER hardware platform,and the data packet was transmitted to the computing server through high-speed Ethernet for post-processing.The experimental platform has realized the complete process of simulation,compilation and operation,and provided a good experimental environment for the real-time processing of astronomical signals. |
