Abstract: | A low frequency (40–150 MHz) radioheliograph for observations of the solar corona is in operation for the last few years at
the Gauribidanur radio observatory, about 100 km north of Bangalore. The array has 32 antenna groups and a 1-bit digital correlator
system consisting of 1024 channels is used as the back-end receiver. This paper describes the latter and results of the associated
system tests. |
