An array system solution is adopted in the paper to face the problem of separation of superimposed signals by performing blind source separation. A five channels receiving station has been implemented to provide a large dynamic range, wide bandwidth and fast sampling, with a proper array of six independent antenna elements properly designed to give a sufficiently wide covering pattern. The source separation algorithm is fully described and the experimental results concerning the characterization of the array elements are discussed.
