How to realize the data acquisition system and processing f-or the 0.7-1.4 GHz solar radio spectrometer at the Ynnan Observatory/Chinese Academy of Sciences is presented in this thesis. The instrument, being under construction, adopts a program of combining multi-channel spectrometer and auto-correlation spectrometer and 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 controlling synchronously of the multi-channel 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.
