Description
Summary:The paper presents the results of design and testing non-imaging mm-wave sensor aimed for remote detecting contrabands hidden on a human body under cloth. It operates in passive direct receiver mode at the range 80-100GHz. The unimodality approximation has been suggested for applying in the algorithm of detection. The antenna system of the sensor is based on horn antenna integrated with focusing dielectric lens. The sensor has demonstrated detection probability up to 100% in laboratory environment for the tested samples both plastics and metals hidden under cloth at the distance up to 3m with spatial resolution about 5cm.
