摘要
本文论述了 0 .7～ 1 .4GHz太阳射电频谱仪数据采集与处理系统是如何实现的。正在研制的此仪器采用了多通道频谱仪与自相关频谱仪结合使用的方案。首先 ,本文详细讨论了自相关频谱仪的原理 ,并介绍了北京大学研制的自相关频谱仪的结构。在此基础上着重讨论了多通道频谱仪与自相关频谱仪的同步控制的解决方案 ,以及大容量数据采集实时存盘的解决方案。最后 ,介绍了我们为数据预处理采用的一些方案。
The data acquisition and processing system for the 0.7～1.4 GHz solar radio spectro-meter at the Yunnan Observatory is presented in this thesis.The instrument,being under construction,adopts a program of combining a multi-channel spectrometer and a auto-correlation spectrometer.Firstly,a detailed discussion is made for the principle of auto-correlation spectrometer,and the hardware structure of the auto-correlation spectrometer built by Peking University is introduced.Based on the first part of the thesis,a solving program of synchronous controlling the multichannel and auto-correlation spectrometers is put forward.A solution for the large capacity of data acquisition and real-time storage is found.And finally,some schemes for the data pre-processing are given in this paper.
