Analytical results and tradeoffs are reported for an aerosol lidar system that is intended to serve as a referee during testing of standoff bio-aerosol detection systems. The lidar system is still under development by Dugway Proving Grounds -- results from the operational system are not included in this paper. The recommended configuration of the lidar system is to use a 1064 nm lidar in elastic mode to measure the concentration of the aerosol, and a 355 nm excitation to measure the fluorescence of the bio-aerosol. Both of these measurements are important in scoring the performance of the systems that will be tested at DPG. Performance tradeoffs and predictions are presented primarily for the elastic mode lidar. The elastic mode lidar is designed to make measurements out to ranges of approximately 15 km. The UV fluorescence mode of operation is intended to support discrimination of bio-aerosols from non-biological aerosols, and is only required to operate at a range of 1 km. The optical design of the proposed telescope supports dual wavelength operation, allows for effective TV camera imaging for test and alignment support, and tailors the optical overlap function for the UV and near IR lidar to optimize the performance of both subsystems.
Contamination avoidancerefers to the military doctrine of avoiding or minimizing the effects of Chemical and Biological (CB) threats. The location, identification and tracking of CB hazards are also major concern for Homeland CB defense. Several advanced detector systems for both chemical and biological threats are being developed for the Armed Services. Current test equipment and methodologies are inadequate for the complete evaluation of these emerging detector systems. Improvements are needed across the entire test spectrum from agent-simulation correction studies and equipment upgrades to field testing techniques. The Contamination Avoidance Detector Test Suite (CADTS) project is funded by the Central Test and Evaluation Investment Program (CTEIP) under the auspices of the Director for Operational Test and Evaluation (DOT&E). This agency is responsible to DoD and congress for the adequate testing of any military hardware before release to the warfighter. This paper discusses the issues involved in CB testing and provides an overview of the characteristics and status of the key capabilities that were selected for funding.
