A Prototype Digital Correlation Receiver for Two-element Interferometer Experiment

介绍了用于双天线干涉实验的数字相关接收机器的构成和信号处理过程。

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 Mi-Iz 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 simulation of signal processing of the digital correlation receiver is given.
