Millimeter (mm) and sub-mm wave radiation is
increasingly becoming a region of interest as better methods are developed to
detect in this wavelength range. The development of sensitive focal plane array
(FPA) architectures as well as single pixel scanners has opened up a new field
of passive detection and imaging. Spectral signatures of objects, a long
standing area of interest in the Short Wave Infrared (SWIR), Mid-Wave (MWIR)
and Long Wave-IR (LWIR) bands can now be assessed in the mm-wave/terahertz (THz)
region. The advantage is that this form of radiation is not as adversely
affected by poor atmospheric conditions compared to other bands. In this study,
a preliminary experiment in a laboratory environment is performed to assess the
radiance from targets with low infrared signatures in the millimeter
wave/terahertz (THz) band (<1 THz). The goal of this approach is to be able
to model the experimental results to better understand the mm-wave/THz
signature of targets with low observability in the IR bands.
