基于IBOB的射电望远镜宽带数字频谱仪系统的设计与测试

内容简介：简述了基于IBOB和Xilinx System Generator平台的射电望远镜宽带数字频谱仪系统的设计与应用:给出了双路400MHz、2048通道、16IP输出数字频谱仪系统的具体设计方案,并对该数字频谱仪器的性能指标进行了分析和测试,验证了方案的可行性;最后初步讨论了滤波器设备对后端系统的影响.

Abstract：In this paper we describe the design and application of an IBOB based Wideband Digital Spectrometer System.The spectrometer system is basically of dual-pole,400MHz working frequencies,2K channels,and 16IP output.The specifications of the spectrometer are analyzed and its performance has been tested.We also verify the feasibility of the system design,and discuss the impact of the filter on all back-end systems.
