21st century Radio Astronomy at frequencies below 1 GHz will be dominated by arrays of thousands or millions of elements in configurations which are dense or sparse, regular or random, delivering data to powerful digital back-ends. High performance, specified by parameters such as the effective aperture and system noise temperature, will be crucial to achieve the ambitious survey speeds and sensitivities demanded by astronomers. In this paper we analyze the different trade-offs and difficulties… CONTINUE READING
