Brazilian Decimetric Array

The Brazilian Decimetric Array (BDA) in Cachoeira Paulista, Sao Paulo, Brazil is a 38-element radio telescope interferometer working in the frequency range of 1.2-6.0 GHz. The final baseline will be 2.27 km in the East-West and 1.17 km in the South directions, respectively. This instrument will obtain radio images from the sun with a spatial resolution ~4x6 arc seconds. A second phase of the array, adding another 21 antennae to the existing five, is planned to be constructed during 2010. This will be followed by a third phase of construction later on.
