Many acquisitions (in telecommunication, geophysics, remote sensing, non invasive control etc.), are nowadays carried out starting from antenna which can load single sensors or multicomponent sensors. Processing of such data require specific processing as multidimensional filtering and array processing. From varied examples, we present these different multidimensional filtering and analysis and main technique in DOA.
