Brazilian Decimetric Array (Phase-I)

Abstract

An East -West, one-dimensional radio interferometer array consisting of five parabolic dish antennas has been set up at Cachoeira Paulista (longitude 45°0 20 W, latitude 22°41 19 S) for observations of the Sun and some of the strong sidereal sources by the Instituto Nacional de Pesquisas Espaciais (INPE), Brazil.
