Today's highly technical battlefield environment dictates the need
for a method of standoff target identification, which reduces risk
to personnel and equipment. It is widely known that a given
material will react differently to incident radiation than a
dissimilar material. Certain materials may respond specularly while
others tend to be diffuse. By measuring these responses, materials
can be identified by comparison with a known database. One method
of building such a database for target recognition is by employing
an active multispectral bidirectional reflectance distribution
function (BRDF) measurement system. In the following text, such a
system is developed and tested using a 1.5m and 2.0m tunable
source. The system does not yet meet the desired 1.0m range;
however, all major system components with exception to the source
are well suited for this entire band. A detailed description of the
components used is presented along with recommendations for further
research. This particular BRDF measurement system implementation is
the direct result of a previous attempt that encountered numerous
errors. These errors were primarily attributable to nonlinearities,
attenuation, and misalignments in the equipment utilized.
Considerable effort was expended in order to reduce these anomalies
mainly through component replacement. A comprehensive error
analysis is presented for this system along with recommendations
for a new system, which should reduce these abnormalities and
improve data integrity and collection efficiency.
