LASER BASED STAND-OFF DETECTION OF BIOLOGICAL AGENTS
Figure 11: LMCT WANDER LIDAR.
Combined measurements of multi-wavelength depolarization ratios and differential backscatter parameters
assembled in an appropriate discrimination algorithm have demonstrated the ability of real-time day and night
discrimination of biological simulants. The current WANDER system has been operated in an eye-safe mode
and has demonstrated the appropriate sensitivity for an early warning system.
6.0 TEST CAMPAIGNS
6.1 Montreal Trial: CIFAUE 06
The CIFAUE trial, standing for Characterization of Induced Fluorescence of Aerosol in Urban Environment
was conducted at the Montreal garrison Longue-Pointe, located in the East part of Montreal, Quebec, Canada,
the last week of September 2006. The pursued objective was to obtain the basic characteristics of induced
fluorescence from aerosols present in an urban environment and its evolution with time. This field trial was
organized by DRDC Valcartier and the British and Canadian stand-off systems were present. The CIFAUE
trial included four phases, each one dedicated to the characterization of a particular area of interest (AOI):
1) Traffic interchange;
2) Harbor facilities;
3) Freight classification yard and industrial/commercial quarters; and
4) The Olympic stadium area (Figure 12).
The aerosols present in these specific urban AOI were characterized during an entire night for each one of
them, from about 8 PM to 5 AM.
