Description

In San Juan, Argentina, the new China–Argentina Radio Telescope (CART) is currently under construction. This will be the biggest single-dish radiotelescope in south america with 40 m diameter. As part of this project, a new digital backend is being developed using the RFSoC4x2 platform. Taking as a base CASPER Simulink blocks, the team is implementing a spectrometer for H I spectral line observations. Data is acquired with the RFSoC4x2, transferred to a server via a 100 GbE network, and processed in real time using GPU-based FFT computation. The processed spectra are then stored on the server for further analysis.
