Abstract: The concept of using chemical sensors for remote surveillance of vehicle activity was evaluated through field and laboratory studies, and consideration of the state of the art of current chemical sensor concepts. Reliable detection of vehicles was found to be feasible at downwind ranges up to several hundred meters depending on the type of chemical sensor employed. By use of a two-sensor array, detection independent of wind direction was highly successful at reduced detection range. False-alarm rates in remote areas were virtually zero due to low levels of exhaust chemicals in ambient air. Potential was shown for classification of diesel and gasoline vehicles by using a classifier unit consisting of two detectors. By trade-off analysis, it was determined that the condensation nuclei, surface adsorption, and Honeywell ionization sensors showed most immediate promise for development as vehicle detectors. Recommendations were made on additional work required in development of chemical sensors for Remotely Monitored Battlefield Sensor System (REMBASS) applications.
