  The Multipurpose Interferometer Array Pathfinder (MIA), developed from the
Argentine Institute of Radio Astronomy (IAR), is a radio astronomical
instrument based on interferometry techniques, designed for the detection of
radio emission from astronomical sources. Phase one consists of 16 antennas of
5 meters in diameter, with the possibility of increasing their number. In
addition, it is equipped with a dual polarization receiver with a bandwidth of
250 MHz, centered at 1325 MHz, and a digitizer and processor for the
correlation functions. For the development of this instrument, a three antenna
pathfinder is currently being built with its positioning control, radio
frequency systems, acquisition and processing stages. This paper will describe
the concept design and their current progress for each stage.
