Description
ARGOS is designed to carry out various types of scientific observations, from time domain to image domain, from spectroscopy to pulsar searching. A versatile, cost-effective and scalable backend system is essential to such a dense interferometer. In this report, we present a bottom-up backend system design for ARGOS pathfinder. It consists of processing units from the stages of digitalization, channelization, beamforming, correlation and data product distribution. The viability of these systems has been successfully proven in various astronomical instrumentation. The making of such a system will demonstrate its capability and gather the feedbacks from the scientific communities, providing valuable knowledges on scaling up the system from pathfinder to the full ARGOS implementation.
