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).
University of Virginia Remote Sensing Experiment • Sponsors: NSROC, NASA, VSGC, SEAS, VEF, MAE. • Previous mission launched from NASA Wallops Island on an Orion single stage sounding rocket. • Future experiment: video camera, and five photodiodes for ocean chlorophyll measurements • Gas filter correlation radiometer for measurement of methane in the stratosphere
Mostly undergraduate project, 18 students + 1 grad student in AY 2001-02, over 60 during the last 4 years. • Interdisciplinary, including remote sensing, telemetry, space technology, mechanical design, system integration.(Shown L/R: Gaby Laufer, Jeff Dawson and Sarah Armstrong)
