A Prototype Digital Correlation Receiver for Two-element Interferometer Experiment

For designing and building Chinese Spectral Radioheliograph(CSRH),we have carried out a two-element interferometer experiment.In the test,a prototype digital correlation receiver has been designed for the signal processing below the 200MHz intermediate frequency.In this paper,we describe the design of the digital receiver,which includes high-speed ADC,bandpass filters,mixer,delay line and one-bit correlator.Finally,a simulat ion of signal processing of the digital correlation receiver is given.
