Abstract This paper presents a rotating W band radar performing a full body scan of persons which are moving with constant speed below the radar. The radar consists of a FMCW module sweeping the frequency between 96 GHz and 99 GHz by a varactor tuned VCO. The transmit and receive modules are fabricated in split-block technology using 100 nm metamorphic HEMT MMICs. The used 4 channel receiver operates between 84 GHz and 104 GHz and an average noise figure of 3.5 dB. Polarimetric measurements are carried out for the detection of oblong objects such as explosive tubes. |
