A device for the detection of concealed objects comprising: a microwave sensor module (10) adapted to emit microwave electromagnetic radiation to a target and to receive the reflected signal therefrom; a front end module (11) adapted to generate and acquire the microwave signals corresponding to said electromagnetic radiation; a conditioning and analogue digital conversion module (12) adapted to process the signals from said front end module (11); a logical processing and control unit (13), associated to said conditioning and analogue digital conversion module (12), adapted to provide the possible alarm following the detection of the presence of a concealed object; a user interface (14) adapted to communicate to the operator the results of the measurement performed by means of an appropriate signalling means and to receive settings and commands therefrom by means of appropriate data entry means; a power module (15). Said microwave sensor module (10) is adapted to transmit and receive an electromagnetic signal according to two separate polarisations spatially oriented by ninety degrees one with respect to the other. |
