The chance of suicide bomber attacks against troops in the Theatre of Operations is currently quite high. Most of the
time checkpoints and compound gates are not equipped with the appropriate equipment to screen for potential suicide
bombers. The ultimate solution would be to be able to perform stand-off screening under various weather conditions
whilst avoiding contact between Force Protection personnel and potential suicide bombers. Radiation in the millimeterwave
and the lower Terahertz range, having the useful property of being able to penetrate clothing in addition to fog and
rain, makes it a clear candidate for imaging in this situation. A study has been made simulating real case scenarios to test
practical detection performance and stand-off distances at a range of frequencies in this band, the results of which will be
presented.
It is well known that millimeter-wave technology provides an important imaging capability through clothing and adverse
weather conditions, among others. Alfa Imaging has undertaken a project to study the different applications of mm-wave
imaging. An important part of this project is the measurement of material properties of a number of clothing and
packaging samples in the frequency range from 40 to 306GHz. This task has been undertaken by the Antenna Group at
the Public University of Navarra using an ABmm Network Analyser. The resulting data has been analysed and is
presented in this paper along with example images and conclusions on the ideal operating frequency for the various
applications studied.
