Date Acquisition and Processing System for the Solar Radio Spectrometer

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.
