Abstract

The paper describes millimeter wave (MMW) sensors designed for detecting both metallic and nonmetallic objects placed on a human body and hidden under clothes. The sensor is based on the synchronized detection principle and estimating a power of back-scattered signal from hidden objects. Time-gating algorithm combined with preliminary determined threshold level has been implemented in order to reach detection probability of ~ 90% or more for metal and plastic hidden objects at the distance up to 3 m.
