Abstract:

The Department of Defense DoD has an urgent need for the development of sensors for early warning and protection of military forces against potential chemical and biological CB attacks. Unfortunately, the current standards and protocols used to evaluate CB sensors are not adequate and, this inadequacy hampers the development of new sensors as well as the proper evaluation of current sensors. In order to address these shortcomings, there is a need for a set of sensor metrics and measurement protocols by which the efficacy of CB sensors can be properly judged. Following a simplified vulnerability and threat analysis, the Study found that there is an extremely large uncertainty in the required sensitivity for CB sensors. This uncertainty in the required detection sensitivity strongly suggests that there is not a single ideal sensor sensitivity for CB agent detection and that, depending on the acceptable false positive rates and other sensor attributes, different sensors with widely different sensitivity capabilities may have useful roles in the defense against CB agents. In addition to identifying CB sensor metrics and measurement protocols, the Study Panel produced ve key findings, which are 1. Sensor testing and characterization is inadequate. 2. Potential threats span a very wide dynamic range 10 exp 5 in concentration. 3. ROC curves are essential for sensor development, testing and evaluation. 4. Sensors should allow for multiple operating modes. 5. Sensor requirements are not well defined. The report details these key findings and makes subsequent recommendations.
