摘要

The Square Kilometre Array (SKA) project is an international collaboration aimed at building the world's largest radio telescope, with eventually over a square kilometre of collecting area, to be deployed in South Africa (mid-frequency array) and Australia (low-frequency array). The Central Signal Processor (CSP) receives signal from 197 antennas (in SKA1 MID Telescope) and up to 8 beams from each of 512 Low-Frequency Aperture Array stations (in LOW Telescope) and, in each telescope, simultaneously cross-correlates signal from each pair of antennas/stations (to produce the full-polarization visibility spectra), searches for pulsars and transients, and performs precision-timing for known pulsars. The CSP, in each Telescope, consists of the three major sub-systems each of which performs a different signal processing task, namely: i) correlation and beamforming, ii) search for pulsars and transients, and iii) pulsar timing. The fourth CSP sub-system is responsible for the overall monitor and control.
