Standoff detection in a fixed military installation: some test results

A standoff detection of atmospheric tracer dispersion in a military installation, using active and passive remote sensors, was demonstrated in a field test. System performance was evaluated at various atmospheric conditions, different forms of tracer release and different rates of release. Source locations as well as sensors positions were varied between test. A network of point detectors was used as an additional mean to map tracer concentrations, especially at locations not accessed by the remote sensors due to the complex nature of the installation.The test results are presently in a process of evaluation, some of them are presented here.
