This paper is the research and development including the system design and the prototype system building of the wide-band digital autocorrelation spectrometer system for radio astronomy observation, which will be used as back-end signal processing unit of the Dual channel SIS receiver at Taeduk Radio Astronomy Observatory. So in this paper. we performed development of the high speed digitizing sampler, the circular memory buffer, and the correlator module for the 400MHz wide-band digital autocorrelator.

Recently, TRAO Taeduk Radio Astronomy Observatory is developing wide-band digital spectrometer for radio astronomy, which will be used as back-end signal processing unit of Dual channel SIS receiver. So in this paper, we performed development of high speed digitizing sampler for the wide-band digital autocorrelator, which can perform sampling and quantization on pseudo-random gaussian noise with the maximum conversion speed of 1.5 Gsps..

This developed system will be use at TRAO after the housing and some calibration.
