| Abstract: | 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 200 MHz intermediate frequency.In this paper,we describe the design of the digital receiver,which includes high-speed ADC,band-pass filters,mixer,delay line and one-bit correlator.Finally,a simulation of signal processing of the digital correlation receiver is given. |
