Abstract
Embodiments of the present disclosure relate to a system for spatially detecting foreign bodies within a product. In some embodiments, the system includes a conveyor means adapted to convey said product through a scanning region and a plurality of antennae arranged transversally to a crossing direction. In some embodiments, each antenna is adapted to transmit an electromagnetic scanning signal adapted to propagate in said scanning region, so as to diffuse in said product. In some embodiments, processing means are adapted to generate a first set of values indicative of dielectric characteristics of said product. Further, said processing means are adapted to compare said first set of values with a second set of values that indicate dielectric characteristics of said product in the absence of foreign bodies, wherein each antenna is adapted to transmit said electromagnetic scanning signal in a crossing time interval, according to a predefined transmission frequency.
