Properties of sensors for domestic defense applications
Sensitivity existing passive remote sensors, Fast (0.1-1 sec), Multi-chemical (weapon agents + simulants), Robust – few (or no) moving parts, no fine
alignment, Simple to operate, Output easy to interpret, Low cost (low level of approval), Low energy (commercially available battery), Imaging capabilities (desirable).
